"excellent overall"4.0 starson by bobodunno
Pros: weight and build
Cons: washed out screen
Summary: Great semi-rugged notebook with a quality build. Fanless design equals silent computing. Grateful for the standalone page up and down keys (not so on the latter models, Y4 and Y5) that I use extensively when web surfing.
More glaring weakness is the washed-out screen and its narrow vertical viewing angle. Memory upgrades (MicroDimm format) are also prohibitively expensive.
