I've been running the 64bit edition of Windows 7 Ultimate for about 2 months now and so far very pleased with it. I've switched to 7 full-time so I can get a better feel of the OS as I did not embrace Vista. Taking quite a bit of getting used to but at least things are much easier to find and the new taskbar features are a great improvement. Another nice default feature is including a lot of codecs within Media Player. I was impressed that when I attached my USB drive all of my music file formats (ogg, aac & mp3) were capable of being played without looking for and subsequently installing add-ons and such. My only complaint thusfar is how poorly VMware Workstation 6 performs with more than 1 guest running. Luckily I still have my Debian drive handy for when I need to do intensive testing. I'll be back again soon with updates on my pilot of 7.
UPDATE 12/10/2009:
It's been a few more weeks and I'm still running Windows 7 full-time. We have a couple others in the company that are running 7 now (32 & 64 bit editions). I've also upgraded my Vmware Workstation to v7 and noticed that cleared up a ton of issues as far as compatability and such. I do miss my Debian install but for right now everything with 7 has been incredibly stable and now all the tools are at my fingertips for domain management and such. I've been tinkering with Media Center - not entirely on the bandwagon for that. It's a clunky interface to manage all of your media and what-not but to be honest, I prefer doing all of that myself without all of the layers, bells and whistles.
