Personally I like it. It did take me a couple of weeks to tweak and configure things, but overall I like it now better than XP. Demographically, I am a 46 year old Dev. So even an old guy can learn new things. I cant really say it runs any slower as I have 2 identical dev boxes, one running XP and one running Vista Premium, both Core 2 duo 6600's with Radion X1650s. I cant speak for games but dev and bus apps run well. On another note, I had to start using voice recognition as we are developing software that will employ it. I was frustrated by it at first, but... just like typing, got better at the commands and as the computer trained to my voice, I find I now talk as much as type. It did take about 3 weeks of actually trying to use voice to achieve this. but it is a new skill. I dont use voice with the XP machine as it is not as mature.
