WOw, congrats. Just saw your post!. I've been following the Pi channel since it has started. You can install XBMC on it,and you it as a media center for your HDTV, and maybe power it off the USB port of your TV. :)
By the way if you want something with a more easier interface rather than DOS, why don't you give the Raspberry Pi Fedora Remix a try?
I tried everything to get XMBC to work correctly and that is still a no go. It is unable to play any movie i try off of my network drive and it will sometimes play music, However most of the time it just fast forward though the songs at 2x speed no mater how you try and play it.
I am using raspberry pi debian right now.
I tried using the Fedora Remix installer... Oh god never again. It locks my computer up and i have to do a hard reset. And after my raid array is doing verifying i have several blocks that need to be repaired. And i make sure to select the SD card... I think it has issues with raid arrays. Because for whatever reason it basically attacks one of my physical drives and starts removing data. Lucky my array is really good at fixing missing data.
I found a Logitech multimedia keyboard with built in track pad that is working really well right now and only takes up 1 usb port for the receiver. I had to pair the receiver and keyboard in windows but after that was done it worked very well for the pi. http://bensoutlet.com/products/logitech-k700
and the receiver can handle other devices as well... However XMBC does not recognize the multi media keys correctly and i can not reprogram it to use...
I am also currently running everything except the monitor off of a rechargeable USB battery and a solar panel. i have in my window. I want to find a USB powered monitor that can be used with HDMI but they seem to not exist. They do have USB monitors but they will not worth with the Pi yet. But they are getting close...
But my goal is to have a fully working "Computer" running just off my solar panel and the Dual usb 8000mAh battery one port for the pi and the other for the monitor.
