I broke down and installed Windows 7 Ultimate tonight from my MSDN subscription downloads. It's running on an Acer Aspire 5601LWMI laptop. Dual core 1.7 GHz processor, 1 GB RAM and 100 GB hard drive. The installation experience was pleasant. I had to search far and wide for Acer's TI flash driver for Vista, but otherwise, no irritants to speak of.
Performance is good. IE 8 has locked up multiple times, so I downloaded FireFox 3.5, which has delivered a much better experience than IE 8. Foxnews.com in particular seems to give IE 8 fits. I've tried IE 8 off and on tonight and my results are spotty at best. I'll try to give it a better workout tomorrow.
I'll fill in any blanks as I gain more experience. Wireless networking is a breeze compared to my experience with my son's laptop and Vista. Installation of both Office 2007 Ultimate and Visual Studio Team Edition 2008 went smoothly. All in all, not bad. I have to rate my experience as trouble free and much faster than I anticipated.
I will probably upgrade to 2 GB of RAM, but this was something I had planned to do.
By the way, I am a software developer. I don't really push hardware the way gamers would. I just want code to compile quickly, and Windows 7 doesn't seem to have hurt the speed of VS 2008.
