Just read a great article on USB Memory projects at PCStats.com
A lot of tips:
- boot from a USB drive
- run Linux
- email encryption
- format with NTFS file system
- creat permanent folders (must read!!!!)
- run Arcade games
The permanent folders is a real eyeopener. Create a folder on your hard drive and mount your USB device there. It means the end of the drive letter assigning agony.
