1. Retina Display - More accurate editing and viewing of photos on the go without having to inspect only 1440 X 900 or 1680 X 1050 pixels at a time at 100%. I use aperture and photoshop, so support is not an issue (pending the upcoming ps update). Outside of those two apps, retina support is a bonus, but doesn't really factor into my decision. - When doing software development on the go, switching to an extended work space resolution will be wonderful. 2. Smaller form factor/weight. It's no macbook air, but it's an improvement. I'm a big strong dude, so I imagine for me it'll feel about how a macbook air feels to my wife. And she loves her air's portability. I hefted the retina in the store, and I'm pretty sure it's going to pass my toilet test.... sitting on the toilet, one hand holding it, one hand using it. (Holding the rMBP) 3. Dual thunderbolt ports and HDMI out is kind of nice to have. I'm sure I'll put them to use eventually. Regrets: 1. Hard Drive Space - I'm going to have to break down and buy a good external RAID setup, as apposed to my single external backup drive. I'm going to have to archive and organize my stuff more often. I rationalize this regret by saying to myself that I need to get better at my organizational skills anyway, and this will force me. I was on the verge of needing that external raid anyway, and have been taking far too many chances with unbacked up data. - I have a windows desktop for gaming, but I'm going to be sorely tempted to try games out on this Retina display.. which makes me sorely tempted to install bootcamp/windows.. which makes me worry even more about the precious little hd space I have! 2. Afraid that new hardware technology that hasn't been time tested may have unforeseen issues over time. I'm a gambling man, hence the poor backup behavior in regret #1.
