I have an Acer s3 like that, It's sturdy as fuck. Haven't had any software issues. I did delete all of the Acer bloatware, which there wasn't much, and have had no problems. Keyboard feels nice, keys respond well. Touchpad is average I would say, I hardly use mine though. Screen is pretty good too for what it is, it gets super bright if you like that stuff. If you care about the speakers on a laptop go kill yourself. If you want to know anything else just ask. But yeah, basically it's a cheap macbook running windows 8.
I've always wanted to try a Vaio like that though
