I'm seeing more and more companies getting ready to move to Vista. I've had no problems with Vista and dislike working in an XP environment. Seems so old and I find myself missing the whole search in the start menu.
In fact that is one of the problems with the search in KDE4's new Application Launcher, their search only searchs things found under Applications, and prompts to run a web search.
I love the whole CTRL+ESC to launch the start menu, then start typing what I'm looking for and bam get it. I use the mouse less, and have remove all clutter from my desktop (all shortcuts) as I don't use them anymore. Rock on Vista.
