What does one use the charms bar for? I've been using win8 as my main OS for over a year and I literally don't think I've used it once. The only obvious things the charms bar does I find easier and quicker to do with keyboard shortcuts. For the record, I despise all the Metro stuff and would cut it out if it were easy to do so.
