I have been using iDevices since 2009, never had a problem with the home button. Two weeks ago I started noticing that the home button on my iPad is not as responsive as it should be, sometimes it acts as if I never pressed it, sometimes I have to press it harder. So far this only happens like 1 out of 10 times (other 9 times it works). Does the home button issue get worse with time? Should I replace it? I am a bit worried that when they try to replicate the issue, it works for them (and they might think I am trying to get another iPad so close to warranty expiration (march 18th)).
