I'm hoping especially for some updates on the e-ink side. Right now, it seems like they did not entirely finish with the annotation abilities in landscape mode (and, in addition, when moving around in a pdf file. From what I can tell, it doesn't all you to move around the document while the pencil is enabled). Also, I'd really like to see them fix some of the sdcard issues. If this is the truth, they are pretty awesome for finishing the update, especially given that they have a limited staff and are no longer actually selling the product.

I wouldn't worry about installing Ermine Beta. It's a pretty solid release. I haven't had ANY problems with it. Plus, 2.2 is so much better than 1.6. You have no idea. The addition of the JIT compiler makes thing so much faster . . .
