Well, I'm a new owner of a MacBook Pro 13" and the Hard Drive is only 160GB I believe which is plenty of space for what I use it for but I would much rather have my Music/Movies/Pictures and all media separate from that space. I was just thinking of getting a portable External Hard Drive for all of my media but then I could also upgrade my 160GB drive to let's say a 500GB Drive and do away without an External drive. What would you do? Upgrade your existing internal HD or get an External HD? The MacBook Pro usually just stays on the desk anyways so an External HD wouldn't be any inconvenience to me but if I wanted to just unplug it and go will that harm anything? Also, there is plenty of External Hard Drives available right now and I was wondering if any were better than others? I just want something basic, portable, and works with a mac. No firewire needed, USB is fine with me. I was really looking at the My Passport from WD and was wondering if the non Mac Ready versions work with a Mac anyways? Also, has anyone heard of or experienced iomega? http://go.iomega.com/en-us/products...rtable/prestige-portable-series/?partner=4760 I would appreciate any feedback!
