I hate to sound sappy, but I'm really loving Vector!
I have previously tried vim-latex on Ubuntu and Debian, on a faster machine, and, somehow it has never worked as well as it is now, on Vector, on a circa 2000 laptop. The major stumbling block before was the insertion of references and citations, which was buggy at best. I have no idea why this is working better...but it is!
The ratpoision-flavour of this thread has become a little tainted...
