There’s much more to Yahoo than just email and messenger. Their finance section is still one of the best. Also, people stay in yahoo pages much longer than most. MSFT doesn’t need an Earth version from Yahoo, they already have a kick a$$ version of their own. Yahoo still have 22+% market share in search, so if MSFT want to go head to head w/ GOOG, they have to get at least closer than where they are now. 9% is where they are at now + 22% from YHOO and you have 31%, much closer to GOOG 50+% than where they are now.
Regards to XBOX, it’s doing just fine. Wii is in a completely different target than XBOX. The one XBOX needs to keep an eye out for is PS3. Wii is for cheap game play that can just have some fun at party. XBOX and PS3 is all about high-def, online game play, and media extender. Windows is losing out to OSX and Linux? Last I check, Windows is still the king of OS, like it or not.
