I'm pretty sure mine is a full keyboard. And I don't believe your laptop weight for one second, RoD.
One of my friends has a tiny laptop, and while it's mighty light, the screen and keyboard sizes just aren't worth it for anyone else who tries to use it. To each his own. If it's really that cheap and you don't plan on making it your primary, then I guess as long as it's light and works, it should be fine, right?
