I Just put Windows 8 on my Acer Windows-based tablet PC. I've been running Logos on WIndows 7 on this tablet and it absolutely stinks. Logos needs to incorporate touch based scrolling rather than be dependent on the non-sizeable scrollbars that it currently has. One should be able to swipe upwards, downwards, or sideways and have the Logos screen move with the swipes. Has anyone at Logos looked at the SDK with an eye towards making the viewer touch-screen friendly? It shouldn't be too difficult for your engineers to incorporate touch even on Windows 7. See the MSDN pages for "designing for accessibility"! If you need some assistance in making this product usable, I wll be glad to help in my spare time.
