We have two powerful desktops of recent vintage, a pre-SB Win7 laptop, a Win8.1 IB laptop and a SB HTPC.
We also have a iPad air for my wife purchased last December.
My wife uses it rather than her phone for reading, browsing and playing games but very seldom for anything else.
Neither my daughter and I see any use for ourselves of a tablet of any flavor at this time. I doubt this one would be upgraded unless it was physically damaged or otherwise died.
