You only need to spen more time to use a new tool like Linux, if all of us only use any tool (Linux,MACOs, Houdini, Maya, etc …) because we know it and we don't want to know anymore the would be impossible to know new things.
I know that for many of us is very difficult to spent time testing new trhings, but, at least for me, I have seen that if I knoe that the new tool is probed to be better, the time spent learning it is time I save in the future, this has been my experienced with both Linux and Houdini.
Don't get me wrong, I'm constantly and stubbornly learning houdini along with all goods it provides, and things which are worth time spent on learning eg scripting.
But with linux there is a completely different story because being a 3d animator you just don't have to know how to fix all of them little errors.
The knowledge you gain over certain level is only a time loss because “oh in the next version they'll change it” and the fact that you are so proud of yourself because you found that after uninstalling package “x” because it did not cooperate with current version of whatever and adding a file here and there your cd rom works all right, is just a plain misunderstanding.
I was a very happy linux user for over a year, after long fights I succeeded in many things and houdini was working like a charm (I used suse so I had to create a simple script for it to set the variables and run some services). But a lot of things were just not working properly, wifi once starting once not (yes I checked with all ifconfig iwconfig rcnetwork status rcnetwork restart route and all of them), external harddrives did the same, mp3 players and digital cameras did what thye wanted, network went dead after installing 10.1, problems with raid because of something, filesystem madness between windows and linux (I know about about ex2ifs and that something for ntfs but hey can you say “corrupt data”

).
After all I came to an assumption that either I'll uninstall this shit and start working or all that I'll become will be a medium skilled home network administrator.
Most of these linux problems empowers you with redundant knowledge.
Now I'm back to windows and curse on memory problems with houdini, but that's houdini problem
