I need a Windows Tablet/Hybrid/Convertible for School

Okay, so I've been recently looking through tablets and what not looking for a device, but can't find one.

Originally I wanted the Surface Pro, but the 4hr battery life kinda just screamed no. The ASUS line of tablets are quite pricey for what you get (VivoTab is $1000, and has the Atom while the Surface Pro is the same price with the Ivy Bridge).

I'm using it for note taking, doing my assignments, web design, and computer programming.

My budget is $1200 tops. Could someone please make a suggestion? :)
