Well this is some very welcome news. I actually had my passport picture taken today so that I could go down to the states and pick up a Nook Color. (and also to travel but the NC was the motivating factor.)
Guess I'll be waiting to see how the Vox is but unless it's got some fatal flaw I can't imagine that I won't be getting one.
The whole reason I wanted the NC was to sd-root it so I could run the kobo app anyway. I use it on my phone already and I'm very happy with it. My phone runs Android 2.3 and it seems to offer everything I'll want in an ereader OS.
Now my only question is... can you turn off the little green light at the top?
