This looks like a troll post, but this is actually good advice. Don't try to force a good Ruby environment on Windows. Instead, merely edit your source code on Windows, and use PuTTy to SSH into a Linux machine that runs your development Ruby on Rails installation. This will also help enforce best practices like keeping your source code in source control instead of hacking it bits-to-metal on your local machine.
1) Don't try to get through a Boston summer without AC
2) Don't try to code 18 hours a day on a 12" laptop
sub lesson to point #2: Don't try to code Rails 18 hours a day on a Windows laptop. It's a joke.
