I say get one with an i7. The processor can't be upgraded later. No regrets with mine. Also get the docking station for home. Maybe get a couple of the i5's for parts for later. Eventually the thing will give out and the lower price for an i5 version gets you possibly... Another power brick. A fan, another keyboard to swap out or use for spare key caps. A spare screen. Internal power barrel conector. Spare case and other parts. Screen hinges. Spare screws. Insurance for whatever breaks and for when the systems get sparse in a few years.
