When the iPad 2 comes out, I'm going to sell my MBP and switch to the iPad 2 as my primary computer. I evaluated my use of the MBP, and realized that just about anything I do on my MBP, I can do on the iPad, especially if I buy the keyboard dock. My only concern is file storage. I have a bunch of Word documents that I am going to need to store once I sell my MBP. Is there any solution for this besides buying a backup drive? I want to be able to access these documents quickly the way I would on my MBP. For example, I keep a spreadsheet of my personal expenses, and would need to update it daily as I do now on my MBP.
