What Win8 Laptop Should I purchase?

Hey all,

I've been having some difficulty finding online which upcoming Win8 laptop would best suit my needs. I'm currently a student, and I'd like something that can run with a bunch of pages open simultaneously--internet, spotify, word, etc--without slowing down. I'm also one that tends to have a ton of tabs open while researching a topic and writing a paper.

Ideally, I'd like to spend less than $1,400. Would a WinRT Hybrid Tablet/Laptop work well? Or do you guys predict it'll freeze with say 4-5 different applications open?

Another concern I have is that it seems like a lot of these Win8 ultrabooks have only 4GB. Is that a legitimate concern with Win8 or is the OS expected to be super-efficient?
