I have picked up my Focus on Monday right after the store opened. All in all the purchase experience was pleasant, the sales guy knew quite a bit about the device and he told me was going to buy one to replaces his iPhone 3g.
As far as the store setup goes, they had 2 devices on display. I can't say I was too impressed with the wall setup and everything, that big touch display for demoing the OS was not working.
So far I haven't seen any other Windows phone device in the wild. One guy at work that is considering buying one is still thinking about it.
