Dunt even bother thinking about a mini then. either get a desktop or increase ur budget to get a full size laptop.
Mini laptop is for people who need emails on the go. and full Facebook.
I used my uncles didnt find it worth it, i jst used it to upload fb pics, other then that my Nokia e63 does all the work for me.
Increase ur budget to Pkr 45k+ (compaq c2d) or pkr 5k0+ (dell core i3)
