Can't find it anywhere. The online Microsoft Store says 'coming soon'. When's that? PC World only seem to be selling them in black or purple. Maybe magenta.
Hard to find in the US as well. I went to two MS stores yesterday and they are sold out of blue. Finally found one at a Best Buy... it was their last blue one.
To be honest, if someone bought me one from the US, I'd be happy to pay for the shipping. No idea why they're not available - I thought it was their most popular colour. And while that would explain the 'sold out', it doesn't explain the 'Coming Soon'.
