Went to the Apple Store hoping they would have the Hi Res 15". The only had the standard res, which I wasn't happy with as a I have a 15" C2D, or should I say my wife now has. Even though I love the portability of my 15" , after playing with the 17" the screen real estate was tempting. Going from 1440x900 to 1920x1200 is quite the adjustment. Since the store didn't have any 15" Hi-Res, the manager gave me his assurance I could exchange the 17" for the 15" within the 2 week period with no restock, if i decide the 17" is just too big. That was pretty cool of him... Right now, I'd say its definitely an adjustment everything is so small, but I'm sure I'll adjust over the next few days, but its so awesome how much more screen I have.. I love that.
