Re: 4. Doesn't support Windows Phone...
Even as a very happy WinPhone user, this is reasonable.
A tiny percentage of people have a Pebble, my guess is more technically minded people too.
I am guessing they would more likely be higher end Android users in any case.
I doubt they would sell even a 1000 to WinPhone users in the UK.
Mind you, I would consider one since the battery seems to last long enough for decent use. I can't really thing of a use case though. Perhaps a xmas pressie for an offspring or two though.
