Koder: It's a code editor app for the iPad, which is a little like throwing a manual transmission in a Prius. There's probably only a handful of dudes who would want such a thing. No matter though, Koder for iPad has a lot of what you'll need to geek out: syntax highlighting, a snippet manager, tabbed editing, find and replace, keyboard shortcuts, FTP, Dropbox, iDisk and local storage, etc. $6


Wacom Bamboo Paper: It's an iPad app that turns your iPad into a digital notebook (or sketchpad). Ideally, you would use it with Wacom's Bamboo Stylus for the most pen-and-pad-like experience. But even without the stylus, your finger is perfectly suited for writing as Wacom has built a superb app that smartly registers touch-it really does feel like ink is bleeding from your fingers (or stylus). The app gives you one 'notebook' to write or draw in with an option of three page types, three pen widths, six ink colors and a slew of undo options. You can pan around in the app, save a 'page' to your camera roll or even print it out. Free, until June 30

It downloads the video to your iPad so you can even watch videos offline. It doesn't support YouTube but it's a great way to keep a stash of your favorite videos on the ready. Free
