Whenever they do a mild update like this, it makes be breath a secret sigh of relief, because if they ever do get around to doing a major overhaul, I'll be forced to buy a new system!
Outside of the multi-touch addition, I was also a bit unimpressed by this. I didn't have any expectations, but it seems like Apple is always sitting a few months behind everyone else in terms of the latest common hardware. For example, the processors now go up to 2.8, but Apple is still at 2.6, even though 2.6 was already an option before this update. (and who's going to pay $250 for a 0.1 boost in their processor??) And when you consider the fact that 2.5" drives are now up to 500GB, you would think they would have at least offered a 320GB drive as an option. But the most you can get is 300GB, and that's only for the 17" model. The 15" only go to 250GB.
Oh well, it keeps me content with my current MBP, so I should be happy for that. Looks like people in general aren't too happy as Apple's stock is continuing to fall today.
