Microsoft products are like Lego's. You don't always get the pieces you want in a set, but they plug together nicely, and can be centrally managed through Active Directory (very robustly, I might add).
Everybody out there always criticizes Microsoft when they find another company (the flavor of the year) who has a better Lego piece, or two, than Microsoft. It's touted as the best invention ever, and promoted as the downfall of Microsoft.
But as it turns out, it's not a Lego piece at all. It's a K'Nex piece. By itself, it's wonderful and awe inspiring. But when you want it to play nicely with the thousands of Lego pieces you already own, good luck!
