> I think the world needs a strong Microsoft again

It's extremely dangerous to think if Microsoft as weak. They have enormous profits and revenue - far, far bigger than Google, for example - that are secure far into the future. They are willing to plow this money for an almost indefinite amount of time into any product to brute force it to success (see Xbox) and they are willing stoop lower and employ underhand tactics to an extent that nobody else in the industry will match. So fear not, Microsoft is a long way from weak. We should worry a lot more about the possibility of them actually becoming completely dominant again than we should worry about the relatively benign prospect of them becoming weaker.
