If it's for Facebook, almost any will do and the Macbook Pro or Air may be a great choice.
If gaming, then http://www.notebookcheck.net/Alienware-15-Notebook-Review.136667.0.html or such.
My current laptop is an HP Pavilion and it's on it's last legs. I would like to get a new one but I really don't know what to get. I've been told by a local store that HP aren't very good anymore and that I should be looking at Asus. Many other friends have recommended getting a MacBook pro. I would appreciate any insight and recommendations I could be given on this website. I'm holding out for Black Friday deals, but I'd like to have some models in mind to see if I can find a deal.
