REALLY LATE on this on man XD but as for what they intend to do, thus far all that we know on the cards is integration with WP7 and XBL. Which are welcomed features to be sure, however not enough to warrant such a massive price tag. Thus its safe to PREsume that MS knows something we don't. MY take, just as Google has gmail phone chat, it's own mobile OS and even phone, MS needs a GOOD app that will do the same. Integrate into online voice chats with WP7, XBL but maybe even become its own telecom.. google is invested in PHYSICAL infrastructure, so why not?
