I put on a new installation of Vista RC2 a few days ago onto my brand new Dell Precision M65. I do have to say I'm highly impressed by the various additional options in Control Panel and task manager, a lot more diagnostic & reporting functions. The side bar while not anything that hasn't been done before is still excellent, as of course is the Winkey+Tab
At the minute my side bar shows a clock, weather, calendar, cpu/memory meter, batter meter, Remote Desktop Connection quick-launch, feed reader and BBC radio selecter/player. Tis nice.
Also worthy of note is that on this new laptop, a clean install of both RC1 and RC2 picked up all my hardware without a hitch, no need for me to go chasing drivers which I was impressed with.
But I do have to say that it absolutely EATS memory. With a couple of explorer windows open, a couple of web pages and maybe a small installation routine in the background for instance, it uses anywhere between 700Mb to my full 1Gb of RAM and the processor usage constantly jumps and never goes below 10-15%.
I also find the start menu very slow to show program sub-folders.
Scrolling long web pages in Firefox and IE is hopelessly slow and jumpy. The CPU also goes around the 40-70% usage mark when doing so. Unless this is down to drivers for my nVidia Quadro card; I downloaded drivers for it from the nVidia site which then say 'operating system not supported' during installation...
dwm.exe (Desktop Window Manager) sucks over 120Mb RAM in a lot of cases if I have even a handful of windows open

I know it's supposed to take a lot of RAM to save CPU usage but that just isn't on. Especially when the rest of Vista is already sucking all the RAM it can. Of course I could turn off the Aero theme but I'd rather pay for another 1Gb of RAM than be without the specia effects
