i have the Kindle and Borders apks . tried them last night and they work fien. Ill be posting them for download on my site soon. I also have the NYTimes, USA Today, Engadget, Pandora, Skype, Aldiko, FB Reader J, BeamReader and Adobe apps so far. I thought I had a working YouTube APK as well but it wouldn't load. Ill have to search some more for it.
I actually ran out of space on the SD card I was using

So i didnt get a chance to try the Fennec browser.
