Microsoft Surface...
It'll break within months, you'll end up with a sh*tty refurb, it'll be broken on arrival, the support will be the usual outsourced rubbish, and after 7 devices you'll have to wrestle microsoft in a pool of mud to get a new one, which will arrive with similar fault developing, at which point you'll give up, put it on a shelf and never use it again.
Been there done that. It sucks. It's really nice hardware but they don't design/build the internals well at all. Also, £3k?!?!?!!?!?!?!?!?!?!?!?!?!?!?
