Laptop on a stick

Program that'll allow you to cram all your internet settings, emails, MSOffice settings, and other programs, straight onto your USB hard drive or flash disk! Now all I need is more than 16KB free on my portable hard drive...

I've already got GTA:VC and Warcraft III running off my portable, so email and more important things are the next most logical steps!

With software like this, who needs 3kg laptops?
