Windows 7: Getting a new Laptop

Hey guys,
I'm saving up for another laptop, While i am typing this I am using a mac book running Windows 7, I've used this computer for a long long time and its just geting to the point its hacing lots of problems. (They are hardware) The disk reader wont even read! so Its time for a new one

I am looking at the dell Mini netbooks, as I am using my computer at school and they are easy to bring around. and aswell I can use it while playing video games (Have like Gamefaq open)

I would like to have 7 on it, Or is there another computer better for the job? I would like something small tho, and Cheap.
I am also going to get an Imac 27 inch and put 7 on that,

I just like the looks of macs lol
