    Hallelujah!



    It's about time a laptop have a drive as easy to remove as from a Dell!

    Corporate America has needed this for discoveries and Sarbanes-Oxley.

    Thank you Apple!

    And how about a full size backlit USB keyboard for my iMac ? I'd give up my full sized wireless keyboard for that and pay nicely for it too.

    Today I purchased two Macbook 2.4Ghz machines with backlighting. Overall I am impressed with these machines but was surprised to find a remote was not included. My iMac remote works fine with the MacBook.

    The stuff about the memory is totally information free. Yes we know that they say that Apple say 4GB max for both MB and MBP. The question is does the hardware support it? I would think there is no OS limitation because MacPros already support greater than 4GBs memory.



    Does anyone have any solid information. Put aside the fact that there are no 4G SIMMs, they will come.

    Apple stopped including remotes with MacBooks at the last MacBook product update. They're listed as an option when a MacBook is bought online at the Apple Store for only $19 more.



    Not including them makes sense to me. If someone has more than one Mac, why would they need more than one remote? If another one is needed, it can be purchased. Plus, not including them with new MacBooks reduces costs - increases profits somewhat.

    They're available now. They're just not priced where the average mortal can afford them.

    Don't you mean a hard drive as easy to STEAL, just like a Dell? Not sure if this is such a great idea. Now the hard drive can be stolen within seconds, rather than having to remove the entire back cover and series of mounting screws. Even the prior MacBook required slightly extra effort to remove the drive. Now a system with confidential data can be compromised in seconds.

    There can be two limitations:



    1. The OS limits the amount of RAM accessible. This is unlikely, since Leopard is a 64-bit OS that has been purpously developed to overcome the 4GiB limit that plagues the 32-bits OS. Yet, that limitation might be enforced in the BIOS and not overcome by Leopard. In this case, an other OS might give different results.



    2. The hardware limits it, that is to say there is no spare address lines on the RAM connector. Might be. In which case there is simply nothing that can be done. A few years ago, this was simple to test with a plain ohmmeter. Now, you cannot access chipset pins with those BGA packages, so you have to put an oscilloscope or a logic analyser to capture any transition happening eg. on the A32 or A33 signal. That's the only way to be sure the pin is connected to the chipset, apart from, of course, connecting 4 GiB modules.

This is more work than the RAM slots that were accessible from inside the battery bay on the MacBooks, and slightly more complicated than removing the partial cover on the previous-generation MacBook Pro.



    And you can do this without voiding the warranty, right?

    Well actually the 4GB modules are here

    The question is will they work. My guess is that you can install them but the chipset will only recognize 6.8GB (8GB minus chipset and graphics addresses) That is my hope. I just don't want to spend the money before I know it is true.

    As has been mentioned, the lines on the sockets mat not be there.



    Apple could have limited this for the reason of power. 8 Gb will get hotter than 4 GB, and shorten the battery run time.

    This might be true at first, when higher capacities are achieved by stuffing more chips on the module. Now, when the next generation of RAM comes out, the capacity is multiplied by 4 without any significant increase in consumption, because the transistor size is diminished and the leakage also.



    At that, note that Apple pretends that battery life is the same regardless of the amount of RAM installed (2 or 4).

    Regardless, going from 4 to 8 will result in more power being used, as well as more heat.

    Well, I've just checked on the Micron inc. website: they offer 2 as well as 4 GB SODIMM PC-1033. The 2 GB module sucks at most 3.2 A (3.2 A × 1.5 V is 4.8 W), whereas the 4 GB consumption is 3.6 A (3.6 A × 1.5 V is 5.4 W). The net difference is 600 mW. Twice that is 1.2 W.



    On a 5-hour use, it means 4 Ah net difference (2 × 0.4 A × 5 h). I guess it will not hamper the autonomy that much. Given that the typical figures are going to be much less than those overpessimistic estimations.

    I would love to see it being an option for the $1,299 model, too, but people will hardly go for their higher model if they do so. Speed bump etc. don't justify that $300.

    Kind of like how some airlines now make you every single piece of checked luggage. You can justify it just like the airlines do, but in reality it's just plain shitty.



    Incidentally, if you've got more than one Mac, wouldn't pairing the same remote with both of them be a bad idea? Unless you like both of your computers to play music/movies simultaneously...

    The article mentions that the entire panel can be locked, i think. A friend of mine works at an apple store, and says that 4-5 MBPro batteries would get stolen from display models every week over the past couple years. The new ones are behind a cover, which apparently will be locked somehow in the store.

    Someone should develop a gas treatment to deactivate the liquid submersion indicators.



    I'm thinking put your laptop in a ziplock plastic bag, pop a sachet to mix two reagents in the bag, leave it overnight and shazzam the indicators will be permanently white.



    I've been a victim of the whole "sorry we're not replacing your faulty phone because the man at the factory said it got wet" (Never mind that it was partially working!!!) scam one time too many. I'm glad it was only a $79 phone!
