Next3 Tablet

I have a Next3 book and I am having a hard time finding apps. I am thinking about sending it back, but wanted to try to figure it out first. It is a nice tablet but I would like to have more apps that I can use.

How do I find and determine which apps work on it.

Ditto here. It th
e droid based phones can use all the apps, why not the droid tablets?
