So i'm looking for a portable unit to bring to classes and take notes, sometimes some photo editing for websites and typing of documents. I may play a indie game or low end game like minecraft/starcraft rarely aswell. Now I have a deal for a SP2 with type cover and dock for 550 the 128gb version. A new SP3 is atleast 1100 for the same size, 64gb is way too small. I heared about throttling on the SP3, so performance when you push the system hard is basically a downgrade. But i've heard about SP2 wifi issues, and SOD problems.... What would you do in my position, 550 is a decent deal but the catch is its out of warranty. Advice?
