I decided to finally install the Windows 7 RTM today (TechNet)...
So far, so good. there are a few small things (it had a nervous breakdown when it booted with my flash drive still attached, note that it was NOT trying to boot off the flash drive, it just didn't like that it was plugged in), and the graphic effects slightly stutter every once in a while, but other than that it works great.
So far I have only come across 2 apps that don't work, Teracopy, and Vsphere Client. Everything else works a treat. Sadly, Vsphere Client is one of my 'critical' applications, up there with Firefox and Notepad++. Hopefully I can get it working soon....
