Hey guys, first post here, so go easy. I did a search, but couldn't really find fully relevant material for my particular situation. A tl;dr version is at the bottom of this post for those of you who don't want to look through a block of text. I'm looking to upgrade my antiquated 3 year old HP laptop (whose battery will now no longer charge). Having a bit of difficulty deciding which year's model to get, though. A little background first: I'll be a senior in college doing programming work, and only really need OSX for running Xcode. However, after having to suffer 30 minute maximum battery life on lowest settings on Windows laptops for years now, I figure it's worth the jump to MBA/MBP. My priorities are pretty straight forward, battery life first and cost efficiency second. My other needs on this machine will be fairly similar to other college students: as a glorified typewriter for social media and casual use. Battery life's self explanatory. Cost efficiency is my next highest priority, and whereas I can afford to get a fully maxed Retina if I desired, it's overkill. That being said, I'm also not adverse to fully maxing out an Air if it's the best bang for the buck. If I need to do any serious processing capabilities, I have a custom built desktop that can take care of that. The only thing I'm really set on is a 13" screen. That's why I don't think a Pro is necessary for me either, since all "Pro" work can be done on my desktop. I would really only use my laptop to take notes, do Xcode side projects, and check Facebook/Gmail/YouTube, etc. Plus, the 13" MBP has a horrible screen. I like the Retina, but it seems horribly price efficient for what I plan on doing. Plus, whereas I can afford to even replace it if it gets stolen, I'd rather not. I've been looking at a 13" i5 2011 Air with 256GB SSD and 4GB of RAM, which seems to be the best fit, but I figured it'd be worth a shot to ask here. tl;dr version: Looking to get notebook with the best battery life and cost performance ratio. Cost isn't an issue as long as it's price efficient.
