Just tell me when it outpaces c++. How many mono apps are there? How many c++ apps? Mono has a really long way to go before it can seriously challenge C++/KDE. I hope not to be misunderstood, moving away from c++ is somewhat a good idea, but its much too early for statements like this, because how many java apps are there to be outpacet?.
This just adds weight to what I've been saying all along: C# = The Java Killer. Also, there's more java on linux than you think. Hell, Android is a whole platform for java on Linux, which is the dumbest possible thing to do, which is why its failing miserably :-)
