It looks as though the U3 portable software applications bandwagon is starting to gain traction. Not only is there now a U3 Software Central site showcasing all the best in commercial applications and games you can transport from PC to PC on those itty bitty flash drives, but there’s also a new site called PortableApps.com which has some cool freeware stuff like Portable AbiWord, Portable Open Office and Portable Thunderbird. Watch this space, it could get interesting!
