Meanwhile Apple I am told have nothing larger than a .5 TB drive! Anyone know a way around this please tell me.



    my guess no



    the reviews i've read have cheapo SB laptops with 17" screens meeting or beating the 13"MBP in terms of battery life. even with Flash. battery life is one of SJ's fetishes along with thin.



    if i had to guess, then every Apple laptop going forward will only have SSD's. it will keep apple on top in terms of battery life. they can make thinner laptops. and SSD's are expensive which means they can keep the same price points.

    Hmm, putting the 15-month old Core2Duo on eBay looks tempting.

I don't need SSD speeds for my MBP. I simply had not realized there was no 1TB or higher internal for the MBP till I strolled into an Apple Store in Boston a few days ago.



    The HDD is one of the few things you can replace on your own without voiding the warranty. Apple wars that if you damage something whilst changing it it could void your warranty, but that?s par for the course. They even offer PDF instructions on their support pages.
    PS: 12.5mm HDDs will fit in the unibody MBP chassis, just make sure the drive themselves are supported in SW. There were some firmware issues that made at least one 1TB drive not perform correctly.

    Unfortunately in the very latest MBPs the case if the unibody has changed dramatically. There is no longer a trap door for access to the battery and HD you have to remove the entire base and only the battery and RAM are user replaceable items, not the HD now. I was of the same understanding as you and was quite taken aback over this change which I had totally missed prior to purchasing. Unless of course the genius in the Apple store was totally wrong which isn't without possibility I guess! I will call Apple to verify ... thanks for the life line



    edit: I see that that was the PDF for the newest version! Looks like it is a user job! Awesome.

    As a whole, OS X is very easy to hack: it is pretty tolerant with modifications, very modular and ready to run kexts that were compiled out of linux drivers. There is really not that much to it if you have the right kexts for the right hardware.

    That manual I linked to from Apple on how to replace the HDD is from a mid-2010 MBP. They walk you through removing the bottom cover of you MBP, what tools you?ll need, etc.

    I'd wager that if we take a look at how the c2d MBP was stacking up against similar WIndows systems running the same chips, we'll see a simlar jump in battery life. OS X has proven itself more power efficient than Windows time and again, so we'll most likely see new MBPs w/even better battery life.



    Switching the entire MBP lineup to SSD and possibly removing the optical drive as well will mean that much more space for battery and/or discrete video card for their Optimus-esque switching technology. My guess would be that the top end 15" and all 17" MBPs would have the discrete card and switching tech. 13" would be just SB APUs, the lowend 15" would be SB only as well.

    They DO have the source code. The Darwin layer is open source. One you have that running the rest of OS X pretty much just sits on top. Drivers can complicate that a bit, but for the most part the heavy work is all in the open sourced part.

    Yep realized that after a while



    Now I just need to source a 1 or 2 TB drive ...



    update: Apple confirm it is OK to add a 3rd party HD and the genius was in fact not OK LOL My guess he was confused by egg nog and thinking of the battery which is NOT a useable upgrade believe it or not.

    I wonder why they even bother but I guess it's fun to try



    Humble apologies for off track thread.

    I paid $2k for my ancient dual G5 in early 2004. I'm still using it - it runs rather well. Divide $2k by 7, and life is pretty good on my end, even if I added on the $130 or so I paid for the 10.5 upgrade disks.



    (...aren't anecdotes fun? Mine happens to be true, BTW.)

    I find that internet forums are much better at answering such questions. MacOSXHints.com is great for troubleshooting and DIYer questions.

    if the MBP gets 9 hours life compared to say 6 hours for a Wintel laptop 1/2 to 1/3 the price it may be enough for a lot of people to not buy a MBP

    Safari is a ram hog. My 4GB machine frequently runs low. Granted, it can be expanded, but still.

    That is the deal. They do have the source code. You can download it yourself. The majority of OS X is opensourced as darwin. The Aqua based GUI is the primary item that Apple has kept locked up.

    and my 24" imac. cost 3 thousand all said. runs like sh*t with 10.5.6 compared to my dell with ubuntu.

    os x is the new windows. bloated and a pain. even itunes and safari updates are requiring a reboot now. stupid.



    Rubbish, plain and simple rubbish.
