Having someone else do my laundry for about a dollar a pound. No more buying detergent, waiting around, having to find change if you don't have your own washer/dryer, loading/unloading, folding, etc.
There were two in my local area, one laundry stopped offering the service. I assume the labor was too much to support the service, vs all other costs for that particular business. I expect this service to gradually disappear.
Windows desktop: I like http://virtuawin.sourceforge.net/ , provides multiple desktops. It's the only one I've tried that I didn't eventually uninstall in disgust.
