I switched from Vim to ST2 two days ago, and this was precisely why.
At the risk of repeating what you wrote above: strictly speaking, Sublime Text 2 doesn't do anything you couldn't do with Vim, either by installing multiple plugins or writing your own plugin.
The difference is that most of the plugins I installed in Vim are features which just work in ST2. I can't _believe_ I went this long without a robust "find in files" or a project system.
Also, in the ~10 or so years I've used Vim, I've _never_ learned its specialized scripting language. Every time I've tried, I've given up in frustration. You can use another language but you can never truly escape vimscript. ST2 plugins are written in Python.
