    Very cool. The reuse of existing silicon only makes each unit that much cheaper across the product line. Good job, Apple.

    For the current iPhone 256MB is enough for backgrounding. For the iPad, I show very little extra RAM, which is sore spot for my needs. Based on the rumoured display resolution the iPhone HD should be between the 3GS and iPad in RAM usage. More would be better but I think this iPhone will have sufficient RAM. It was also quite expected with the iPad only having 256MB.



    I guess you've JBen your iPad! Any probs? Got a link?

    Along with that Android phones are using generic ARM chips that contain unnecessary components that the phone will never use. A4 is fully optimized only for the iPhone OS. The iPhone OS will be optimized for the chip. That will make both OS and chip lean and fast.

I'm sure Android will get better at this but Apple will have a much easier time of this than all the vendors using Android.

Why manufacture the older model and keep it in production when you have a newer form design and a new processor (A4) for all models. Transfer it all to one uniform design and keep one "basic".



    I'm not sure that is viable. The difference between the devices isn't just a snap on case different CPU/GPU. The entire engineering has been changed. it's considerably thinner and double-stacks the chips onto one silicon wafer. To make a 3GS in the new form that has the same performance specs would still be making an entirely new phone.



    Compare the 3GS logic board with the iPhone HD's LB » image

    These internals look much more complex to build over the previous models. I have to assume this process does cost more and far outweighs the cost of silicon, but with so many million being sold between the iPhone and Touch that it may be like the milled aluminium MBP cases in that no other vendor can feasibly compete with Apple on this scale due to their relatively low sales for their higher-end items.

    And since the iPad is an internet tablet, anything that hampers one of the centerpieces of the device -- Safari -- is a serious misstep IMHO.

But the memory bandwidth doubled either way, because of the A4's new 64-bit memory bus (most likely to help with the 4-5 times number of pixels in the iPad and iPhone HD).

    Now I understand. Thanks!

    No jailbreak needed. I used iStat to compare RAM used at startup and across multiple apps against the 3GS. The display in the iPad needs more RAM for obvious reasons.



    The reason I returned it was the inability to open up multiple pages in Safari without having the pages refresh, even when switching between the pages within Safari. I can open up 8 on the 3GS and not have it refresh even when going to other apps.



    Hopefully it's just a bug in the iPad causing that in Safari.

    iPhone 3GS -- 480x320, 256MB

    iPhone 4G -- 960x640, 256MB

    iPad -- 1024x768, 256MB



    There are just two many pixels to deal with for 256MB to be enough for the iPad and the iPhone 4G in Safari. 512MB would probably be the sweet spot.



    So you are saying that the 4G ratio is too much for 256mb? Not one person here knows that the ratio is, but that being said, have you used an iPad, higher ratio, more hardware and it's butter smooth....sorry but you're comment makes no sense at all.

    There are still things we don't really know, especially about the display. And for me, that's a huge deal. I'd like more pixels, but I'd love OLED. Imagine the extra battery life!



    OLED is still in the running, right?

    Hmmm... I kinda' like that it does a refresh. On my Mac I have a forums bookmark folder that creates one browser window with about 12 tabs for all the Apple info sites. I ripple thru them every few minutes. I must manually reload each tab or manually reload them all (if it's been a while).



    On the iPad, I use the same bookmark folder and ripple thru the sites in a single browser window... I always get the latest info.



    Maybe Apple should provide an option for refresh behavior!



    My biggest gripe is because of my old eyes.



    I would like an option, say a triple tap, that would allow enlarging the content of an area, like a web page, without enlarging the page, itself... Reflow the enlarged content within a fixed page width!



    Sent from my iPad, from the iLibrary, while sitting on the iThro... Oops, too moch information!

    Scenerio: You're on the iPad, in these very forums, typing a reply to someone explaining some intricate technical detail about whatever. But you have forgotten a key part of it or want to get some very specific info or even just some links to supply for them to read up on the topic. So you switch to a new page, Google the info, copy it and then go back to the original page to finish your reply. But when you go back you see what you have typed for a second (since it's just a snapshot at this point) and the page reloads losing everything you just typed.



    That was a deal breaker for me.

    Of course the iPad is butter smooth in speed operations, but I'm talking about memory caching problems that are already presenting themself on the iPad and will likely as well on the iPhone 4G if it only has 256MB.



    Here, Gruber explains it better than I ever could:





    Quote:

    There?s one severe problem in Safari for iPad, though: memory crapping out. MobileSafari for iPhone has always allowed you to open up to eight pages at a time. It tries to keep them all truly open, in RAM, so that you can quickly switch between them. But when it runs out of memory it starts flushing some of the pages. It doesn?t forget the URLs for those pages, and, in recent versions, it saves a static thumbnail image of the rendered page, but when you switch back to those purged pages, MobileSafari must reload the page ? thus, you must wait both for the contents of the page to download and for the page to actually render (which ? the rendering ? often takes longer than the downloading). It?s very noticeable. Switching between unpurged Safari pages is instantaneous. Switching to a purged page takes as long as opening it from scratch.



    This purging problem got a lot better with the iPhone 3GS. The original iPhone and iPhone 3G only had 128 MB of RAM. The 3GS has 256. MobileSafari?s ability to keep more pages in memory is probably my single favorite aspect of the 3GS.



    The iPad also has 256 MB of RAM. But, in my use, iPad?s Safari isn?t able to keep nearly as many pages open as I can on my 3GS. In fact, sometimes it seems I can only have one, and every page I switch to gets completely reloaded. This is more than just annoying ? it can lead to data loss if you have unsubmitted form data sitting in an ?open? iPad Safari page. I?ve run into this posting items to DF from the iPad ? my posting interface is a web page form. When I want to link to the current page, I invoke a bookmarklet which opens a new page with the title and URL fields of the posting form set to the title and URL of the page from which I invoked the bookmarklet. Often, though, I want to switch back to the page I?m linking to copy another URL or a bit of text to quote. Twice so far, when going back to the posting form, it?s been purged and must reload from scratch ? in which case I lose anything I?ve already written. I never run into this problem on my iPhone 3GS when switching between just two open Safari pages.



    The problem is also severe for AJAX web apps, which tend not to be designed with full page refreshes in mind.



    I hope this can be improved significantly in an iPad software update, but I worry that it?s endemic ? that because the iPad screen is so much larger than the iPhone?s, that MobileSafari must allocate significantly more memory per page for the framebuffers. 256 MB of RAM simply may not be enough for MobileSafari to keep more than two or three pages in memory. If so, Apple really needs to consider some sort of caching or serialization scheme rather than completely flushing away purged pages.

    I typed this



    Opened a different browser window, and copied this from TUAW



    http://www.blogcdn.com/www.tuaw.com/...oundtheset.jpg



    Returned to the prior window (this one), and pasted the link.



    The old window opened without refresh... The cursor was in the exact location in the open "reply" text area.



    Just for drill, I did like above, left the reply area open, closed the page, went to email and copied. Closed email opened Safari. The last closed window came up with the reply area as above.



    I pasted this:







    .Hey Everyone!



    *



    I know it's been ages, but I have been traveling like a maniac recently * I am finally back and can't wait to tell you all about my last few weeks









    I didn't even know you could do that!

    No one is saying it's not possible, but it's not consistent. I can have 8 Safari pages on the 3GS open and this has never happened. I can have a 2nd page on the iPad and this happens. Try opening up the 9 pages to rich sites, like NYTimes et al. and see if you can switch between them and leave Safari to use other apps without Safari pages reloading when you go back in. I couldn't.



    You can see from Mazda 3s' comment that I am not the only one who has experienced this.



    Now jump ahead a few months to iPhone OS v4.0 for the iPad with multitasking in full effect. Unless they alter the software to cache and/or be more RAM efficient this problem will be increase over the next year.

    2) copy pasted from another web site that I opened in a new browser window: The best way to experience the web, email, photos, and video. Hands down.



    Watch the iPad video

    All of the built-in apps on iPad were designed from the ground up to take advantage of the large Multi-Touch screen and advanced capabilities of iPad. And they work in any orientation. So you can do things with these apps that you can?t do on any other device.



    3) copy pasted from a non-resident, unopened email:

    Your anecdotal usage patterns are not indicative of everyone's usage patterns and experiences. This was an issue! This was why i returned it! This is well stated among many iPad users, blog sites, etc.

    Wait, you mean there's no actual tabs feature on the iPad? That is such a deal breaker for me. I literally have twelve tabs open right now.
