I have "found" an HP Slate 7 Voicetab Ultra which is basically a rebranded MediaPad X1, the X2's predecessor.
When I say "found", I mean I have been made aware of its existence. I have not found one for sale.
It even has the LTE bands I need.
Isn't it frustrating when what you want is no longer available?
(Ooh err, missus!!)
