By now you know that Alfred does a lot more than just launch apps, right? You can directly command your Mac OS X system from Alfred as well as launch stuff without ever taking your hands from the keyboard, the true power user position.
Did you also know you can send emails, with or without attachments, from Alfred as well? You need to purchase the £15 PowerPack (~$23 USD) to make it happen, unfortunately, but it seems like a pretty good price for such great functionality.
