What a crap biased article!
"Skype has pulled its Windows Mobile client, saying the interface wasn't worth keeping"
From what I've read elsewhere it wasn't as you say, but because Windows Mobile has been installed on such a wide variety of phones by so many different manufacturers that it was difficult to provide consistent quality service for so many different devices. Not sure why that is, but it could be because many of the manufacturers customize the installation for the different models.
Another more plausible explanation is that Windows Mobile is very long in the tooth. Steve Ballmer definitely dropped the ball and M$ is feverishly rushing Windows Phone 7 to catch up as a result. I have to say that Windows Mobile is still very full featured. Yes, it has it's occasional quirks, but I'll take those any day over something limited and restrictive like the Iphone. I'm hoping that Google finally gets its act together with maybe...Nexus Two? No matter what, the mobile phone race is definitely getting interesting.
Bill Ray, be a good little Apple fanboi and drink your Kool-Aid!
