Microsoft used to be THE company that sells software that corporations need (from OS to their office suites). Used to. Now Microsoft is a company clinging onto new versions of legacy software
I agree for the most part on your points. But for major products like Office, we see people here agreeing quite often that if it ain't broke, don't fix it. And that is valid too... it is a good product even now. But sure, now they seem to be more interested in catching up and copying other companies' ideas than innovating; or even being clever and visionary enough to understand which companies have truly good new ideas and products before they buy them.
What I think is ironic in all this, is it is my understanding that Ballmer was at the helm for most of the time when this mental and innovative contraction took place. Even more interesting is that Microsoft stock went up when he finally left. My take on that is that he's not really qualified to make any judgements on other companies.
