Where is Microsoft in all of this? We're almost at iPhone OS 4.0 and Android 2.2 and in the same time Microsoft have managed to ship one minor upgrade (6.5) and talk a bit about how great 7 will be.
Much like the search industry, this isn't exactly Microsoft's forte[1]. I think they see the benefit in shipping something fresh, given that they're not exactly at risk of going much lower.
Floundering, but playing catch up very quickly - the May 2nd release of the SDK was the first to include a dialer interface. It looks like MSFT has finally decided what they want to do about the iPhone/Android "problem".
