Netbooks

Until now I can't decide what laptop do I need to buy. Earlier while I was surfing on the internet, I came across to the website of buy.com and I found a netbooks. Well, I am confused wither to buy a netbook or laptop. Netbooks are very convenient than laptop. Hopefully, I'll be able to decide which one to buy because I'll be out of town though I need to be on the internet all the line.
