I had to hook up my mouse again for some convenience type task as I hauled my laptop thither and yon and did not want to carry the tablet.
The mouse is NOT as accurate as the tablet. I hadn't realized how used to absolute accuracy I had gotten until I didn't have it any more and I kept expecting it. I'd move the mouse and the cursor might move and it might not. And sometimes it would move a lot and sometimes it would move much at all. Now, this mouse wasn't broken and I wasn't using it on some oddball surface, like shag carpet. It simply was not as accurate as the tablet. I'm never going back. Ever. Even for a short trip, I'll haul the tablet.
