I have a 13 inch Acer I purchased in early 2011. Despite its low cost, the thing has run like a charm since day 1. I literally have zero desire to replace this thing at any time in the foreseeable future. It still runs 4+ hours on a battery, which is remarkable, since I use this machine more than 5 hours a day. I have a desktop with twice the processing speed and twice the ram, but for all intents and purposes, it runs almost exactly the same as the little Acer. Unless I am playing a game or running illustrator, I simply don't need the power.
