I have no empirical data to back this up, just a gut feeling that my Surface RT is behaving in a less stable manner. Primarily issues arrive upon recovering from sleep or power saving. The screen reacts to touches eratically, delays seem longer, and in general the device is just less predictable. Having used my RT since day 1, I have never perceived a stability issue until last week. I was actually quite surprised at the consistency in functionality of the 'release issue 1'. I simply perceive less consistency over this past week. I have waited a week to post in hopes that an update would be issued today clearing my inconsistencies up. Obviously there were no updates released today. Does anybody have any insights to my perceptions?
