The usual $/£ currency sting
The price is quoted as $350 but the UK price is £300. At current exchange rates it shouldn't be more than about £220.
I am still tempted thoough as Google have said they won't provide my old Samsung Galaxy Nexus with the 4.4 update as it's now too old. A bit strange really when they say one of the drivers behind 4.4 was to get it working on older hardware so there'd be more convergence of Android versions across handsets. It's not really sending out the right message when they won't keep one of their own Nexus models up to date.
