I got my hands on 7 as soon as possible, eager to get away from Vista. My initial experience was great - Windows Update installed most of the drivers that I needed, and only left me to install a few chipset things. BootCamp has no problem with it, and it doesn't show me any of the Vista Loader crap that it gave me when I was running Vista.

Same with my Optiplex, it worked pretty well with 7, although it never ran Vista. It downloaded most of the drivers on its own.

My apps worked well, including Daemon Tools, even though 7 repeatedly told me it had compatibility issues.

My my PC laptop (Sager 5793) it runs great. No issues.

On my gaming desktop (E8400/P35/8800GT) it runs great. No issues. Doesn't have a management driver for the motherboard (Intel DP35DP) but it's not necessary.

On my unibody MacBook Pro 17", it runs great until it decides to hang the machine, forcing a reboot. This is depressing. All drivers are current, event viewer doesn't even report anything. OS X on the MBP will run into infinity without issue, so I don't think it's a hardware problem.

I do not like the extremely limited windowing system. I really don't. Otherwise it's a fine OS.

Installed today, without problems. Had to install graphics drivers for Radeon 4890, everything else works.

Startup speed for me is the same like in Vista 64, i dont't recognize a speed difference between both.

What i like is the "mouse-over" functions on the taskbar (for example i robocopy a disk, surf in firefox fullscreen, just put mouse over icon on taskbar and the window appears). Also on the right edge of the taskbar the show-desktop function. All in all a good idea, an other approach than simple copy the Exposé stuff.

The wallpapers are nice, weird and funky.
