I upgraded to the Vista release that came out after RC1 on the Dell D620. It installed fine without any problem. The laptop has an Nvidia NVS 110M graphics chip, and I had to install the drivers manually last time for the Aero interface to work. Not any more. Everything worked right out of the box. I'm impressed.
Once the build was installed, I installed Firefox 2 RC 2. Things stopped working at that point, as it became the default browser. Changing it back to Internet Explorer 7 fixed the problem for now. I'm using LiveWriter to make this post. Feed Demon doesn't work similar to the flow that I had developed with NetNewsWire. Its probably me. I'll have to keep using the app to get used to it.
I'm installing Visual Studio Express, but what I really wanted to try out was IronPython. I'll get to that right after these installations.
So far so good. But I don't know how long I can last on a system without bash!
