That is the state of most corporations today, but at best, I would consider Windows a rapidly depreciating asset (in a strategic sense -- I'm sure it will continue to be a major source of cash for a while).
"Microsoft used to control the future of computing. Now they are yet another enterprise software company with no apparent mission except to make money.
Meanwhile Apple/Google/Amazon/Facebook/etc look toward the future"
I disagreed with the part where they said "just another enterprise software company". I also happen to disagree that they have no apparent mission, but that's another story; please forget that I said it :)
So, would you argue my point for a second? Why is Microsoft NOT just another enterprise software company now or in the next decade? I think I can come up with more, "bigger" and more provable reasons that they are NOT than that they are, but could be wrong. And who knows the future? Right now, they're surely not just another enterprise company and the future is not static, it's based on the now.
And to be clear, my "just another enterprise software company" category includes IBM and Oracle, as well. And I imagine Microsoft is still on the top of that list, but I don't think they have a radically stronger position. It is a very profitable position for now, but that wasn't what the original comment was about.
The question is whether they can again "control the future of computing" or just continue to make a lot of money on roughly the status quo (i.e. simply be "yet another enterprise software company"). I can't speak for the original commenter, but I suspect their emphasis was on "enterprise software company with no apparent mission except to make money" rather than "yet another", so that line could probably be replaced with something like "yet another boring, immensely profitable company".
On that question, I think you can make a good argument that some of their footholds are actually a handicap now. For example, Windows and Office make so much money that the company becomes conservative, unwilling to do anything that might significantly disrupt them.
They haven't released an OS without the Windows name in about 20 years now. Even with their mobile OS attempts, it always has Windows in the name. Even the original XBox promotion had a bit of "it's based on Windows" push. And on that line of thought, why hasn't there been an XBox Phone? The smartphone market is largely consumer right now, so why not try a different brand approach?
Yes, Microsoft dominates in the enterprise space right now, but they are losing badly in the consumer space (which will eventually break into the enterprise position) and the cloud space (which is the enterprise position of new companies). What do you see them doing to change the course now?
On a "consumer tech" tangent, IE 11 will finally implement WebGL. Direct3D gave them a unique hold on desktop gaming, paired with a really strong console gaming position. WebGL finally forced them to submit. I expect there are a few divisions that are wickedly pissed off now, and I totally understand why: Direct3D is now in its deathbed.
An utterly dominant, gaming tech position undermined and eliminated in the span of maybe five years.
In the enterprise market, I'd give them a longer timeline, but it's hard to imagine a moribund, hydrogen blimp of that size managing to see (much less avoid) the fireball collapse that's coming.
