Bought high end 15"
I went and picked up the high end 15.
Build quality:
I encountered some flames here for returning two SR MBP's (and a hyperventilating Air) in the last 45 days, but hey, I am not keeping a machine with shoddy build quality. Luckily, I can report that the Penryn machine I picked up last night is not only tight and flush all around, but the screen has no discoloration whatsoever, it is perfect. Hallelujah!
Dropped by the local Fry's on the way home and scored 4GB of quality ram for only $100 and voila! Portable powerhouse.
The only thing I have found the multi touch useful for so far is the history feature in Safari and folders. Other than that I wouldnt have noticed.
I considered the top shelf 17", but an additional 700 bucks for some screen realestate combined with losing alot of portability just didnt seem worth it.
Happy camper.
