Does the MEGA65 contain any kind of lightpen emulation? If so (and if the GEOS version in the making will also be set up with a lightpen driver), then it would be very useful for a touchscreen on a future laptop version. Similarly, when running WinVICE in a window and clicking by the Windows' mouse onto that: then the emulator translates it to a lightpen event for the emulated application at the appropriate X/Y position on screen.
