Answering the first question - the keyboard... pro's type, a lot. It'd be fantastic if they had decent keyboards... full spherical keycaps and travel. None of this flats and scissors mush... I gots to type brackets and braces for a livin', yo.

For the second... depending on your eyes, get the retina display. For most people, its worth it. If you wear coke bottle thick glasses in 2014... maybe not worth it. Fitting more characters onto the screen and having the text rendered ever so properly is lovely for writing code with.

If you run VMs, the i7 is handy. Otherwise, the i5's are pretty rocking as is. I always go with multiple power adapters... but you can stock up slowly on sales and ebay if you're not already living la vida macbook.
