    The second layer is the most delicious layer.

    Actually it depends on your intent. To reverse (or as you called it back) engineer is not illegal but to then use that design (especially if not developed in a 'clean' environment) is considered a BadThing?.



    Edit: Melgross answered first/same time - sorry for the dupe.



    Thanks! revers - back whaterver

    Same here, my spelling has improved dramatically because of seeing the correct spelling. This of course reflects on how much attention I paid in school I still seem to reverse a lot of letters due to either bad typing or some brain disfunction though.

    Refined OS and new processor. What validated evidence do you have that more is needed? And why just another 256?

    No brain disfunction. One hand -typically the right one- is faster than the other one. this is particularly obvious when you are tiered.

    I think it's cool. It shows that Apple can deliver great performance with conservative hardware specs.



    Think of it this way, if the ipad is as smooth as it is with 256mb now, think how nice a later generation with more ram will be.

    The beauty of designing your own chip set as well as the OS that runs on it.

    I find it depends on the person and their ability or intent to learn anything new. Most people I know just accept whatever the system says and move on, never learning the correct spelling at all. If you take the time (as I do and apparently you do as well), to look at the proffered suggestion and learn it, you can improve your spelling dramatically. Sadly, not many bother to do this in my experience.

    That just seems to be the trend in these kinds of gadgets. Video cards, for example, seemed to double their vram with every new generation for a while there. Now it's sort of teetering off until software can catch up.

    Come on now! I'm a big fan of reductio ad absurdum on forums as they can often be humorous but you have to have a valid point first. Do you have or ever had an iPhone? A lot of posters here can attest to the limitations of only having 128MB in the original iPhone and the benefits of 256MB. The 3GS is the curst iPhone that could feasibly handle multitasking.

    I recall that at the WWDC it was explained that RAM/multitasking was not the issue. Multitasking/battery life was.

    I don't think melgross or any other reasonable poster thinks here it's needed. He stated that he was hoping it would be 512MB. Myself and many others thought so, too. Note that he ended the comment you quoted with a statement that wasn't complain or crying out how Apple has ripped us off, but that they likely know what their multitasking can and can't handle. Pretty damn reasonable, if you ask me.



    As for the 256MB addition, that's typically how they scale. It's possible to add 128MB more but I think that when they do add more it will be for a total of 512MB. The why is pretty universal. The 3GS from June 2009 has 256MB, the iPad is more capable likely having apps that utilizing more RAM, and because multitasking is a foregone conclusion at this point.



    There is about 1/4 of the RAM free when I check my stats, which should be enough for an app or two running in the background.

    Like wise people here had real expectations based on current technology. That doesn't mean that everybodies expectations will be realized. But the want for a rational amount of RAM is not unrealistic.

    In this day and age only two types of people would ask that question. One would be a troll. The other would be somebody that is stupid. So which are you?



    By the way if you are stupid that can be forgiven as one can't be blamed for genetic issues not of his making.

    Unfortunately the issue with RAM is very real and of concern to both the developer and the user. More importantly given todays technology the desire for 512 MB of RAM is not unrealistic. Given the design of iPhone OS it is almost a requirement to realize some apps that would have been nice on the platform.

    The iPad certainly feels different. I.m seeing that the autocorection seems overall moor intelligent. I can even type fucking with out correcting to ducking.

    Battery life is an issue but RAM is a major factor. I don't know what they said at WWDC but saying it's a battery drain is a scapegoat answer because we know Apple can't just add denser batteries, but added more RAM is well within their power. Jobs did the same thing with Blu-Ray; it's true licensing was a bitch but the most relevant reasons would make them look bad. It's management speak.



    The 128MB can technically do it the same way net boom with 1GB RAM can technically run a bunchnof apps, but it's not pretty. Even running the background able apps on the first two phones could be problematic.

    I've been reading all the comments about how 256 MB of RAM is not enough. The world that we live in today always goes the easiest way not the best way. Now we slowly learn that we shouldn't only try to make the hardware more powerful but also make the software more efficient. When it gets cold in my house I can turn up the central heating. However, I can also choose to improve the isolation of my house. What Apple did with Snow Leopard is a good example of this whole process. While other developers make software which require more and more hardware resources. Other developers are making their software more and more efficient. More hardware is a pragmatic solution. More efficient software is the ideal solution. Since Apple is a company with great ambitions and a idealistic perspective on both hard- and software they understand this very well. While Jobs is at the wheel they will never forget this truth, and while many others require heavier hardware to do the same tasks as Mac users do, but with less recourses. Thus leaving more recourses free for other processes. I believe that the exact same approach is taken with the iPad. A new operating systems means more efficient software. Back in the days a 1Ghz machine also had 256 MB of RAM. Companies in stark contrast to this vision are:
    • Adobe;

    • Microsoft;

    • Intel.

    Let's wait till iPhone OS 4.0 is shown to us in a couple of days and then judge again.

    I find that a lot of people don't read any more. They also don't know very much about word origins, which is a shame. I guess it's a sign of the times.

    Apparently 256mb is enough because the iPad seems to run everything very quickly with 256mb.



    On what basis are people saying 256mb isn't enough? We're talking about apps *designed* for the iPad. There is no sense in measuring 256mb on the iPad against anything else, save for another iPad, or the *next* iPad.

    I will join in here too as I have not heard anyone else say this before. There are several words that I now know that I have a tendancy to mispell and just knowing can help me correct them on my own.

    However, it a problem for typing on the iPhone, as it has no system wide spell check (outside of the typo correction feature).* Now, when I need to spell a word that I know I frequently mangle, I intentionally miss the last letter to the left or right to see if the iPhone will correct that last letter. If not, then I know I need to try again. This can be effective, but it is a real pain...



    I hope 4.0 has a spell heck in it, so I don't have to go through this...*





    *if someone tells me that the iPhone already has a system wide spell check, I will pull my hair out (and then be glad).
