After looking at the DTrace stuff I saw earlier, Solaris 10 actually looks like an OS I would run!

There are a lot of interesting new technologies in there. Lets hope they really go back to their roots and create a developer CD that allows people to do C/C++ using their tool chains. When Sun first shipped, I believe the compiler came with the OS.
You know, with this, and a few other Real-Neat-Things out there, I haven’t been this excited with computers in quite a while.
