Selfridges said in a statement that the Q10 is its "fastest-selling consumer electronics product ever," and that it sold its entire stock in two hours. BlackBerry itself is mum on the exact number of phones that have been moved, but The Guardian quotes several sources as saying that the Q10's launch is wildly successful; one Selfridges manager saying that the launch was "leagues beyond" any previous product launch, including BlackBerry's more conventional keyboardless Z10.

Looks like there are still people who like a physical keyboard on their phone. I'm quite surprised at this to be honest, I expected the Z10 to be the best seller out of the two. The future may be looking good for RIM/BlackBerry/whatever they call themselves.
