For some reason, all these WindowsRT and Windows 8.1 tablets have been a big let down.
Common problems have been:
- build quality
- thickness
- weight
- battery life
- low memory
- slow processor
- screen quality

And when those downsides are not negated, then there is the issue of Windows. Its legacy support is great, but doesn't bode well for touch. But when you go to use the touch ui, the learning curve is stupendous. Much much worse than Android, which is touted as "not great" at least in comparison to iOS. On top of this, once you pass that learning curve all you see are the cracks in the armour. You keep scratching your head why they designed things that certain way because it makes no sense and is very counter intuitive.

I think at this point if the average person wants personal electronics get a:
- smartphone (iPhone 6, SGS4 or better)
- an iPad (cheap iPad 2, iPad mini 2, iPad Air 2)
- a laptop (Macbook Air/Pro Retina, Yoga Pro, XPS 13, Acer S7, Ativ, Elitebook, etc)

The hybrid revolution never quite happened.
