MS buys Google? Unless the current management is dead, I doubt it will ever happen. There seems to be deep hatred between Balmer and Schmidt.
As for ups and downs. Looks like, for Google, it's always up. The only ones going down are Yahoo. And MS is trying to go up (search business), without much success. So, with Yahoo down, MS going nowhere, there's only Google, stronger and stronger, hopefully enough to withstand any MS assault.
As for Balmer having style, what style? His behaviour appears better suited for someone working at a cowboy bar.
