I bought an RT2570 to use with ubuntu installed on my macbook air.

But the the macbook air is an overheating useless joke and i'm going to bin it.

So i want to buy a new laptop to use with backtrack. I'd like something lightweight which will test WEP securtity "out the box" when i install backtrack.

Is the ipw2200bg still the best.

Which lightweight laptops have this?

Would it be easier to cinfigure the ALFA USB RT2570 or an internal ipw2200gb?
