I was really impressed by the 15" rMBP, but I normally prefer a smaller laptop, so I was really looking forward to the 13" rMBP. Today I got a chance to play around with it at the Apple Store, and I have to say, I was disappointed...The difference just really isn't as noticeable on the smaller screen. I have a 13" MBP now, and although I could see the difference, it didn't blow me away. Not like it did with the 15" rMBP. I also noticed that it was very stuttery when swiping between dashboard and the desktop. Anyone else had a chance to play around with one and felt underwhelmed?
