Tablets can be a royal pain in the arse...
One Win 8.1 Tablet sometimes refuses to respond to the touch-screen inputs. All the various reset processes fail to accomplish anything. Now what?
Well, it requires an On The Go cable, a powered USB hub, a mouse and keyboard, in order to gain access to the GUI to invoke a Repair Windows command. Would your Auntie know that?
Then it needs several hours to reinstall a GB of security updates again.
My Android tablet (Nexus 7) is no less a pain in the arse.
And don't get me started about Apple. They're the worst in my experience.
My many Win 7 laptops are BY FAR my least troublesome gadgets. (Except Win RT mentioned below.)
Tablets are convenient, but can be very annoying.
Afterthought: My Surface 2 with Win RT has been perfection. Hardly any updates, zero problems. Stable as a wood burning stove. Just works. Stability via obscurity.
