Second With all the diffrent Devices It seems like the phones out dated in a month look at the nexus 1 everyone was saying this was supose to be the iPhone killer etc. now it looks like its been a flop and google is no longer officially selling it.
It's called evolution. iPhone can enjoy its annual snail upgrade pace. It's also why iPhone sales are stagnant during the final few months because everyone is waiting for the new model that comes out every summer.
As for the Nexus One, it will be sold in stores now, which will greatly increase its presence. N1 will be released by Vodafone in UK and SFR in France.
