On a whim I grabbed this:
http://itunes.apple.com/us/app/keypad-for-photoshop-for-ipad/id365867250?mt=8It's a keypad app for Photoshop. At $1.99 I thought I'd take a flyer.
WOW was I impressed. A little complicated to get going at first (not for anyone with half a brain, the instructions are great, but there are several steps) you must download an ipad keypress server (free) from their site as well as the plugin file for Adobe, but once everything is installed it rocked instantly.
So what it does: takes the majority of commonly used functions and makes a single press layout with them. Where something should be adjustable, hold for just a second and a dial appears under your finger. So for example: select a layer, then touch the Opacity button. Touch and release, the Opacity dialog pops up. Touch and hold, a dial appears ... spin to select the opacity you desire. Damn well done and a really innovative and cool way to use the pad. Once installed it's a simple click of the server app on the Mac and select the app on the 'pad and you're good to go.
For people with lots of muscle memory around how they use Photoshop it might be a pain ... but having just converted a bit ago from CS3 to CS4 I'm still lost as to where a lot of things are. This just TOTALLY cleared that up, because it's just a click away. So: Left hand iPad, right hand Mouse, use keyboard when necessary. Delightful.
Although I'm not seeing anything yet, if it had a button to convert to an actual finger smoother for blending and such that would be DOUBLE extra cool. Worth a look in any case, since it's pretty novel and well done.
