It's not as good as it gets for one simple reason. Mobile. Ms's policy when behind is embrace and extend. They are almost behind in browser share and are currently not in the running with win phone 7 (that could change rapidly as their offering is on a technical level in the running). In order to compete on mobile they will have to bring their browser upto webkit levels. They will do this as if they lose mobile they become irrelevant in the next 10 years. Mobile is the new desktop and desktop client + office is their bread and butter
