I like my VOX, except whenever I turn it on I have little voices, "I want to play Angry Birds on your tablet", from my 3 yr old, and "I want to race bikes on your ereader", from my 5 yr old, or hubby wanting to play angry birds.
I use dropbox to download since its much much easier then than hooking up the VOX. I also do more reading in Overdrive (for my library books), and Aldiko, my knitting patterns are in Mantana??SP??, and sometimes the Kindle App is better for PDF patterns.
If/when the google.play is open to us, I will seriously consider buying another VOX. My other dream is that tablet that you can easier add handwritten notes on top of print, I think its a Samsung, but hard to justify at this point. A second VOX will end of being used by my spouse and children as a toy.
