The tools never mattered much to me... I've been happy with my jobs when I got along with coworkers and had good bosses.
At the Math Forum, I walked in to "your desktop here was one of our old Linux servers. It's got RedHat 9 on it now. Get yourself a browser, then download NetBeans and CVS and start helping with this code."
At DuPont, I walked in to "here's your Dell. You're not allowed to touch anything since the software's controlled by corporate. Get PuTTY, and choose vim or emacs."
At Microsoft, I walked in to "here's your laptop, desktop and development server. Get online and do a network install of Visual Studio and Source Depot. Then schedule yourself for an interesting training class or two."
