Granny gadget?
This could be a gadget to leave with granny who has no ability with IT / tablets at all.
Because you can fire up Skype or BBC iPlayer etc remotely for them using a free Teamviewer account.
Could even be used a security cam / infirm person monitor at this price point.
IOS / Android - no chance for proper remote control.
Windows 8.1 - proper remote control possible.
