I think it's good news. Considering MS owns the majority of the desktop operating systems with Windows, it's safe to say most people use it over Linux and OSX. That means most Skype users are on Windows. So for people who use it just on the computers, they probably won't even be aware of the difference, except now Skype will probably come pre-installed on computers or part of Live Essentials or something.

It's good for businesses with integration to Office, and gamers for XBox. And, of course, it's good for Nokia, which after they integrated Skype so well into Maemo I'm pleased that it'll be Nokia's next devices that continue that trend, not iOS and Android, where yet another thing Nokia did first gets credited elsewhere.

Frankly, the WP7 ecosystem is shaping up nicely: it has the biggest instant communication name with Skype, the largest hardware manufacturer in the world with Nokia, who also owns the largest mapping business in the world with Navteq. As most people own Windows computers, it's enticing to use a device that will integrate so well. Consdering Elop mentioned that this was now a battle of ecosystems, there's every chance of success.

I wouldn't be so enthusiastic except for the fact that Skype's CEO is still in charge of it under a whole new division of MS.
