Paper for iPad
If you're tired of going all analog on your Moleskine notebook and want to embrace the new hotness, check out Paper for iPad. It's a free app with several brush types availble for in-app purchase, and it looks like it's a ton of fun to use. I have a lowly iPad 1, but if you managed to snag an iPad 3 with the massively hi-res display Paper will be sure to please. Oh, you might want to pick up a stylus, too.
