Not that I have seen. . . Not for business. Business users are very conservative for doing upgrades. They wait for a long time to be sure it is the right thing to do, waiting for others to do it first, and even then they'll wait more.
LOL, I just finally moved off of Windows XP a week ago...and onto Windows 7! Do I feel behind the times? Hell yeah. But reality is what it is.
When you work in a large enterprise, 5,000-10,000 employees, and money is tight, and there are constantly huge IT related projects going on that have more impact and importance to a company than what people are using on their desktops, and money is tight, it isn’t hard to see what will get shoved to the background.
For IT, building and developing the support infrastructure for supporting thousands and thousands of PC’s is no small task, everything from building valid disk images for the desktop support team to the network underpinnings to support it is a major task, never mind the hardware upgrades. Many organizations (particularly in healthcare) have critical legacy applications that cannot easily be transitioned to a new OS.
In a strapped economy, jumping to a new OS in a large company is by no means a done deal because the new OS looks better and runs more reliably. The investment that has to take place in training, updating applications, the loss in productivity as people try to get acclimated to new software...it is huge.
So I agree with Swordmaker, most large companies are pretty conservative on these things, that I have seen.
I have half a dozen machines, all running XP because that is the last system I can run the proprietary software I use for work on.
Pity, too, because I can do what I need just fine with it. The only sad part is that as I resurrect old machines to run it, I can't do a new OEM install because the verifying servers will not recognize the license (maybe the XP ones are done). I have two unopened copies I didn't get onto machines before MS shut down or I'd have them up, too.
