I got one earlier in the year but have never had time to do anything with it. It's sort of not as great as it sounds at first. For $35, you have a device that has to be tethered to a wired network, and has to have a power adapter. (I have yet to find a USB cable in all my mountains of cables that will power it.) The cost starts adding up quickly when you add stuff that's not included, like an SD card. You don't have to have an HDMI cable, since it can pull a DHCP address from your network and you can ssh to it, but if you want to project to a TV screen you'll need one. To made something usable out of the RP, you almost have to add so much to it that you're getting into cheap tablet price range. Any application I can think of would require a battery and wireless network card. If you have a lot of spare parts lying around, I think it would be great as a hobby/tinkering platform. My first project was going to be making it boot up and play a radio stream, as an "instant on" radio device. (But it wouldn't be very portable if it had to be plugged into my network and power strip.)
