After taking a good look at the rMBP in the Apple store I am having a hard time now not buying one. Originally I was going to buy a new iMac but the retina screen on the macbook just blows the iMac's away. Something about using this macbook just makes the computing experience more close and personal than using the iMac and easier to use to boot. If I was to get one it would have to be the next generation as the specs are really going to be epic for a portable computer that would be my first ever proper desktop replacement. Entry level 15" Haswell rMBP: Improved battery life higher core clocks/performance better gpu maybe even Maxwell better integrated gpu more consistent retina screen faster bigger ssd increased ram If Apple can deliver this I am sold.
