For how much FUD Microsoft has to face from both Mac and Linux users, I'm shocked to see them doing the same. There is always one idiot to ruin everything for everyone else. However, I will admit for how much of it they included in the slides, there
are a lot of truths in there as well.
Linux has a long way to go to offer the desktop experience Windows does. It needs to quit being the "Me too" OS it is. Windows/Office offers a better, grander desktop experience, whereas Linux brings almost nothing to the table and lags behind MS and Apple. People criticize Microsoft for changing a lot of things, and doing this and that, but all I have to say is there are reasons for that, Linux has been the same thing since 1998. There is a reason why they do all the studies that they do. Change can be a good thing

Until then, Linux will always remain a niche OS limited to the few who bought it with their netbooks or the 1337's who would rather use it over Windows and Mac. It just doesn't offer much.
