Iomega Prestige vs. Iomega eGo
 

I have been looking for a portable harddrive.
I have found two.
Iomega Prestige Portable 500GB ($124.90) vs. Iomega eGo Portable 500GB ($ 159.90)
I am wondering about the price difference. Could it be because the prestige don't support firewire? I would like to know which one would you choose? If you think there is an other portable hardrive that would be better please tell me. I just want it to be 500GB and to be powered without a seperate powerchord.

Prestige: Iomega- External Hard Drive, Network Storage, Data Storage, Data Backup Multimedia, Removable Storage, Storage Devices
eGo: Iomega- External Hard Drive, Network Storage, Data Storage, Data Backup Multimedia, Removable Storage, Storage Devices

Ps. I have a macbook 2,4Ghz OS X 10.5.4 (if that matter)
