hi there, been using Vista Ultimate for 2 mos. now
the only thing bad about it, is that like previous versions of Windows, it still get slow with frequent usage.
good things, Indexing is built on to the core of the OS, now you dont need 3rd party indexing softwares, making search a cinch.
the so called "Game Console" puts all your games in one location(or folder) it even gives you the rating of that Game so you know if it can run perfectly without lags on Vista.
the Windows Aero(that utilizes the Windows Presentation Foundation subsystem) is a revamp of the UI is really great, it shows a thumbnail(called Windows Live Thumbnail) of each open program you have and Flip and Flip3D makes switching from one program to another easier.
Networking in Vista is also extremely fast, because Microsoft re-engineered the networking stack.
Icons can now be scaled. Just hold Ctrl then Scroll the scroll wheel of the mouse.
Vista is built from the ground up.
There is more to experience than reading reviews and forums about Vista.
o yeah, another con, like XP when it was released, there is some incompatibility with some softwares and hardware, so be sure to check if your software and hardware are Vista capable, but dont be alarmed if your software doesn't work with Vista right now, programmers are working hard to make their apps work with vista, same goes with the hardware manufacturers.
TRIVIA: even before Vista was released, Microsoft already had a codename to the next OS after Vista, actually, they're already making that OS. What's the codename? bad thing I forgot it, I've read it on an MSDN magazine(Asia-Pacific Issue)
Anyway enjoy Vista
