I always unplug! And like some if the rest of you, my machines are worth way more than my computers. I really appreciate this topic. Someone wanna make it even easier and just tell me exactly which one I should buy? I went to look and it was mind boggling-like the detergent aisle. Remember when it was just Cheer, All, and Tide? Crest, Colgate, and Aquafresh was new!? Sometimes too much choice is overwhelming.
