^What they said. Or spend a bit more, wait a few months to actually get it, and buy a
Hammerhead Karoo. Pre-order price (still available right now, but they're about to start shipping the first orders) is about £280 including shipping and all the taxes. I'll be getting mine some time in the spring. A bit of a punt, they're a newish company, but they've already delivered one product to market successfully and the Karoo looks very, very promising & more than a match for the rather more expensive Garmin Edge 1030, let alone the 820. 3.5 inch touch screen, 3000 MaH battery (estimated battery life 10-15 hours, endurance modes might well extend that further), runs Android, full mapping... Oh, and they don't seem to expect end users to be beta testers.
