I for one am happy to see this happen. RealNetworks has a # of good, smart folks who have learned from past mistakes (as does Microsoft) and we're all still learning. Harmony is a good subscription service, though I personally prefer Yahoo! Music Engine for their personalization system.
In the end, I think this agreement will be good for consumers. Rob hints that this could pave the way to better interoperability on everything from mobile phones to alternative OSes. I don't have any data to back that up one way or another, but I do see this as a step in the right direction. What will be telling in the coming year is whether a relationship of trust can be established between key members of the organizations. Microsoft has done it with others (eg. AOL in Media Center). I think it can.
