Last night I even left my powerchord at work when I left. Since tomorrow is ascension day I didn’t take the chance to leave it at work tonoght. I will try to stay on batteries to see how long they really last. Right now (after a couple of hours of use) the battery meter tells me that I’ve got approx. 6 hours 30 minutes left. It feels good! Next week I hope I’ll be able to order a new 7200 RPM SATA harddrive to further enhance my Tablet PC experience.
