I have been trying to cut down on the number of different tools I have to keep track of by 'standardizing' on things that go across as many different platforms as possible. For my Editor, I love Vim. I have installed it on a couple of different Linux distributions, two different flavors of Windows, and at least three different versions of Unix. Vim is one of the first things I install on a new machine, along with Perl 5.8.x, VNC, and FireFox and PuTTY (Windows only).

So far the only problem I have run into with Vim was installing on a Solaris 2.5 box. I had to upgrade the gcc(1) before I could get anything to build. (There were Political Reasons I couldn't just upgrade to Solaris 9 and be done with it. Sigh.)
