By the end of the Labor day weekend (in the US) hot news of Microsoft buying Nokia's devices & services division started trickling in. Now after more than a day or so almost every news site has covered the story and have interpreted it in their own ways. The interpretations range from drawing parallels to Apple buying Next for Steve Jobs (and his ideologies) to Google buying Motorola for its patents and hardware capabilities. Some speculations also suggest that the ex-Microsoft guy Stephen Elop might be a hot contender for the next CEO of Microsoft. Theories of who is benefitting from whom and whether or not Nokia should have gone the Android way in the first place are also flying all over the place.
But to draw a simplistic conclusion, it goes back to what Steve Jobs has always preached, and followed and here is the famous Alan Kay's quote he liked so much, "People who are really serious about software should make their own hardware". I think Microsoft and Nokia joining hands is plainly realizing (agreed... pretty late realization) the fact that profits from software alone are dwindling and the only way to survive in these times is by making your own hardware and to survive and stay profitable you need to make your own software as well. Steve Jobs was a genius and he could predict changing times much before anyone else foresaw and it looks like he was decades early to the ideology in this case!
