Thanks for your encouraging words. They help a lot.
I'll go back and take another look at an Android port. There are a couple of things that work in favor of an Android port: one, I'm quite proficient in Java, so I wouldn't have to deal with the learning curve issues that came along with learning Objective-C. Another, is that I'm just finishing up my first port of Oovium. That port has been fairly painless and I have been taking steps or eyeing changes to the Oovium code base to make future ports easier still.
On the other hand, I'm not sure what the Economics of the Android user base are at this point, especially for tablets. I know the phones are very popular and I'm also aware that the 4th most common search term along with Oovium is 'android'.
At any rate, I'll check in with one of my development buddies to see what numbers he's seeing at the moment are.
