Happy with my Nexus 10, but..
Two things spoil my feelings for the Nexus 10 a touch.
The day after I first started using the device I woke to a dead device. Could have sworn it was switched off, but even so the battery was lifeless. Scary!
The other thing I discovered yesterday - there are no CPU temperature sensors.
Not only did this surprise me, (my three other Android devices have them) but I was surprised by the lack of search results pointing this out. This thread has one of the results
There are a few issues with text size on some of the apps I use, but they will be sorted out in time I feel sure.
All in all a great device, well worth the money.
