Haven't switched the Vega on since the Nexus 7 arrived. Its worlds away in terms of performance and useability. Its been to work more times in the last week than the. Vega has in 18 months. I'm reading books and comics on it, and I only have to charge my phone up once a day now. Yes, if I was watching video on the screen on my own, the Vega's size is an advantage, but the poor viewing angles make it impossible for more than 2 people to watch it comfortably. I'll miss the HDMI out about once or twice a year, and I never filled the 16gb memory card I put in it.
But: it was a great introduction to android tablets, rooting and flashing ROMs, and it still holds up as a good all around proposition, especially with the dock (it may even become a media streamer/remote/alarm clock for the bedroom if XBMC for android runs on it).
