I've found Firefox to be a bit slower compared to chrome these days. I don't know why but chrome feels fast and lighterweight. It doesn't offer as many extensions or addons but it does everything I have wanted.

I wouldn't mind getting a netbook sometime. I love my larger 1920x1200 HP but it is a handful on the couch. I will probably wait for the next round of processors, hopefully the price isn't effected. Price is really the only reason I would consider one.
