Hi,
I have both a netbook and laptop. I bought the netbook in order to work on the go, while my laptop is great it is 17 inches and too big to commute with...I am presently working on my Master's part time, and the ability to work on the go is very important to me. The netbook is great for reading articles, cruising the net, and for short papers/research. It is slower to warm-up, and I can't over tax the processor by trying to open too many windows or try to ask it to do too much at once. I sometimes forget how slow it moves until I use the other computer again. As for gaming, I'm not a gamer...however, one of my classmates is, and recommends the gaming netbook from Dell.
Alienware Landing It is faster, a little more expensive and heavy, but would also be great for regular processing if you wanted something with a little more power. However, if you are talking just about the games from Facebook...I've played those on my netbook/laptop, and although they run a little slower, it is still doable. Best of luck in your choosing,
Marg
