Tom’s Hardware takes a look at the Ubuntu H2 Micro USB Drive. This small thumbdrive is a self contained unit that plugs into any USB port and boots into Ubuntu 4.10. Setting up the H2 is simple:
We picked an ordinary computer system in our office, plugged the H2 device into an empty USB 2.0 port, and inserted the mini DVD into the drive to boot from it. After starting the Ubuntu installation procedure, you merely have to confirm some questions about three times, and the whole process was done in six minutes.
After that the drive can be used on any PC that supports booting from USB media. It features 3 gigabytes of storage space and retails for about ~US$135.
