What you see as a regression I see as an enhancement. My evidence is based on what deployments/pilots talk about when they come give reports at 1cc. When we talk about touchpad problems it often mentioned that the children have a hard time positioning the pointer in general due to the fine motor control it takes. 2 of the apps that our deployments spend a lot of time in are scratch and etoys. Both of these are not completely sugarized apps and thus some of the UI elements on the 200 dpi screen are quite small and hard to use with a fast accel. Reducing the acceleration also has the benefit that when the jumpyness does occur its effect is less because the accel values are less. > * The new kernel (with modular psmouse, with the new code) stays. > * xset goes back to 7/4 0 I think that before you make this decision on xset you need to get some feedback from deployments or pilots that have users in our target demographic. Children. People like Juliano Bittencourt, the guys in Nepal, or Uruguay. I believe Quozl also has access to a small number of children testers. Testing is pretty easy since to test the accel change they don't even need the test build. -- Richard A.
