I have been using portableapps on a 1 gig USB Flash Drive from CFGear for a few months now. I am totally hooked. John Haller has created one of the coolest things ever. I think I could probably ditch my laptop all together and just carry the thumb drive loaded with PortableApps Suite. (The only thing I would add is Portable Skype which is essential.) And the best part? It is free.
