More has been revealed about Windows 7 and its touch screen capability. Reports have also revealed that there was a very high error rate in the early versions of this technology--partly corrected recently when Microsoft engineers redesigned the system so that zoom and rotate functions work specific to the application being used. With this new system, the zoom and rotate functions went from a 75% error rate to a 90% success rate. However even a 90% success rate it too low, as it would frustrate users after frequent use.
