Looking for a laptop

So I've been using an iPad 2 as my only computer for a couple of years now, and I think I'm gonna need to finally get a laptop due to my increased coursework.

It'd have to be pretty cheap, preferably less than $500, or INR 33,000.

The ability to hackintosh would be appreciated.

The trackpad has to be extremely smooth, and aligned in the centre. (Trackpads on one side irk me.)

Battery life should be decent, and a thin design would be nice.

Things I don't really care about -

a DVD drive or SD card reader

the speakers

a touchscreen

Any suggestion will be appreciated

Thanks :D
