Simply put, the market sees more growth in Apple than they do in Microsoft. Microsoft has been trying to grow for a while now, which since they own such as large share of the OS/Office market, means expanding into new markets.

They have had some success with xbox, but overall they are yet to be in the black there. There is still a chance to grow with the online services. If they can get the xbox positioned as a general entertainment devices in enough peoples homes, but it may be too expensive for that. You have google coming into this space now, and they are going to do things very cheap.

Zune hasn't worked out for them.

They lost there way with Windows Mobile, it seems they just forgot about it, just as they did with IE.

IIS has started to falter, and .Net has seen some great growth, but looks like stagnating now as well.

Whereas Apple have some exciting products coming out, that seem to do very well.

On the other hand Microsoft is in a position where they can deliver the best integration of your web, desktop, mobile and living-room devices and has the resources and skill to do so.

They probably don't do it because they are such conservative douche-bags and don't want to threaten their cash-cows, but I wouldn't bet against them in case the money from Windows / Office stop flowing and they end up in a position where they either compete or die.
