The only reason this product is not getting 5 stars has everything to do with the Android OS.  We have both Apple and Android in this family; I personally prefer Android's flexibility.  The only issue really is that the tablet is able to download apps made for the phone that don't operate properly on the tablet.  The coming upgrade to Android 4.0 (ICS) will solve this issue.  Otherwise, as my first tablet, it is everything I had hoped for.  Easy, intuitive, solid quality equipment.  The tablet itself is really of good quality; the screen response is as I would expect and the unit feels solid in hand.  It is slightly heavy, but not a primary concern at all.  Overall, I would buy this tablet again. 

Question: What is the unit of the devices?
Answer: the unit feels solid in hand
