I can thoroughly recommend an Acer. I've had mine now for just over a year, and it's a great lightweight fully-spec'd piece of kit, with a genuine worldwide guarantee. Used it both on the modem and wifi in our rental villa last year.

Check the www for prices, there's a huge range to choose from.

I use a dell 400 for work, and personally I find the wifi less capable of finding a signal than my Acer.

btw - I apologise to anyone else who found my earlier joke about mac users offensive, which was the reason my first post was removed.

Cheers
