Apples IPad

I am in the throes of tech envy! Some of my friends have bought the Apple Ipad 2. I have played with them a bit but they seem just like my IPod Touch only bigger. I cannot seem to justify the cost just to have a bigger screen for what I can do on my Ipod. I have decided that I will wait till the Ipad comes out with a USB port or a slot for a SC card. I need someway to access data and transfer data and documents without having to connect to a computer. Especially since Apple only wants you to sync with 1 machine only! I mean really, I have several computers that I use for different tasks and the ability to connect an Ipad to each machine without having to load ITunes and then wipe the Ipad just to put a file on it would be key for me.
