Hi.

The IOmega peerless drive is far to expensive. The cartridges, which are effectively IBM notebook drives without the electronics, are more expensive than the corresponding (fully featured) IBM drives. In the case of the 20GB model, you could acquire a firewire or USB case for 2.5" drives plus the IBM drive for less than the cartridge alone, and you would surely be more independent, because you could use that drive without an iomega docking station/cradle on almost any PC and/or Mac (at least in the USB version).
For mobile data storage, I either use the empeg (using ftp) or a 3.5", 40GB drive in an external firewire/ieee1394 case, which is basically the size of a book (half letter size, about 1.5" thick). smaller amounts of data are transfered either by zip or CD/RW.
