This portable hard drive is a great solution when you need to transfer files from PC to PC. 20GB is a decent amount in my opinion, and it's very easy to connect. The only downside is that it's not USB powered like a Zip portable drive. That means you also need to carry an AC adapter, which I think makes it less portable. Additional adapters can be purchased from the iomega website. Leave one at home and one in the office and you have full mobility.
