Microsoft is a failed company? They have had products that failed (so has every other successful company). But with a $269 Billion market cap, I don't think they are failed company as of today... Maybe they are becoming irrelevant, it really depends on your perspective. Like it or not hey still have the seventh most visited site in the world (live.com), the largest browser market share @ 27.95% (as of March 2012), and 85% of the OS market.

Don't get me wrong, the only thing I use from Microsoft is their optical mouses (I think they are the best IMO). But they are far from a failed company. Barnes and Noble on the other hand...
