There are ways around it. You could output the analytics code after a second page is accessed based on IP. This should filter pretty much most of it. Of course it will detriment the value of bounce rates too in ga but you could extract it from the logs.
I don't know if the recent changes in the google SERPs have anything to do with it, if they amplify it. In some cases now, I cannot get straight away into a site clicking the found links and have to enter them manually mainly because of the extensions I use with the browser although I had no trouble couple of weeks ago. Maybe there are similar problems with portable devices but I haven't run any tests yet.
