It really depends on what kind of development you do. It's great as long as the tools you need are actually supported. And the tools would presumably work the same on linux so it's more a matter of what kind of system you prefer to administer. I just switched to linux on my main machine after 12 years due to getting hooked on the jetbrains crack. That and the lack of dart-sdk/dartium. I'd switch back if those two things got supported.
PyCharm/RubyMine/etc. aren't officially supported, you might be able to get them to work by manually doing the same things the intellij port does. But pure IntelliJ IDEA works perfectly.
I tried the community edition a while back. Can't remember much by now but it definately was'nt the same experience as the commercial one. (Actually I'm using the phpstorm edition).
