I wanted to try MavensMate. Force.com IDE is like this comfort food you can't live without, but you started to wonder whether there's a better dish to keep you healthy.
So after thinking about it for quite some time, I finally got around to actually do it today. I don't have a Mac, but MM should work for Windows too. I downloaded Sublime Text and MavensMate, followed the instructions (solved some little issues along the way), and ... it didn't work. "New Project" from the menu did absolutely nothing. So I opened the console in Sublime and noticed the error message about needing mm_workspace information. Eventually I found the issue - basically the portable version of Sublime Text does NOT work for MavensMate on Windows, because MM would be at a loss when it needs to find the settings file. I couldn't figure out where the connection.py file is to modify as suggested on the Github issue page (maybe because I'm using the x64 version of ST3) so I just reinstalled Sublime with the regular Windows installer, and things started to work.
Overall the first step for adopting MavensMate was a bit more involved than I expected. It's a young tool - I told myself.
