Hello, which base model should I buy for general use as a student? - Late-2013 refurb for $1529 - Mid-2014 with edu discount for $1899 I can get by with 8GB RAM, I use a VM, but mostly just one instance at a time. That's about a $400 difference after tax. With a new model out next year, hate to buy new right now. Is there a compelling reason to get the 2014?
