I don't use ":back" (because using "H" from normal mode is better) but having a command line in your browser is awesome! Firefox has much better address bar than Chromium (which seems to be designed to maximize the number of Google searches from the browser), which does smart auto complete with fuzzy finding and search engine completions for lots of sites and vimperator makes really good use of this. Example use case (which I use daily): press "o w<tab>" which is short for ":open wikipedia" and then type in your Wikipedia search, and you get smart autocompletion from Wikipedia. Much faster and better than doing a Google search and clicking the first link (while looking at a few ads).
