DropBox :)
Also if you haven't, please use this link as I (and you!) get more space: https://www.dropbox.com/referrals/NTY5MTMzMDY5
It allows you to sync files across computers/phones(iPhone, Android, Blackberry)/etc. So its pretty much a secure cloud system where when you put a file in the folder it syncs it onto the other devices you put dropbox on as well. Mobile Me for everything if you will. Put music, files, documents, everything.
Here's what I did: Install Dropbox on everything I use (Home PC, Work PC, and now Droid).
So give Dropbox a chance. And if you do, please use my referral link! You get 250MB extra space as well!
Thanks Everybody
