Like everything except vundle. (I use tpope's pathogen) Pre-packaged vim on github is a very nice way to distribute.
Vundle has proved a significantly better system for keeping things managed and uses the exact same approach and code as pathogen. It's hard to criticize vundle and support pathogen since they are so similar.
vim +BundleInstall! +qall
Vim still opens but could be useful if you're trying to automate vim somehow.
2. Vundle is too heavily Git/Github-centered for my taste.
