Hi everyone, I've been looking heavily at the Slate 500, but the wait and lack of customer support from HP is really turning me off from it. I need a device that can be used in the field to write notes while walking, as well as mark up PDFs, powerpoints, etc from a desk. I'm wondering if anyone can give a first hand experience to if this is the tablet for me, and if you see any concerns with it. Also, I heard that there is a bump on the back of this, does it prevent the device from resting comfortably on a desk? Thanks.
