You're right of course regarding their incentives. But at some point the customer's choice won't be to also buy the HD from Apple, but to buy the whole laptop from another manufacturer ?! They should either flat-out forbid swapping the HD (and you watch for the justified outcry then) or adhere to the standard. Are you saying you wouldn't mind Apple continuing down a road where you can't even put a standard hard drive in your Apple laptop anymore? I'm still hoping it's just a bug, by the way...
Oh, I haven't bought anything yet. I'm still running on my trusty white Macbook from '06. It cracks but at least it's working.
I'm certainly in the market for a 13"/15" MBP though. 17" is way too big for me.
