I am asking this based on some posts in another thread and wanted to ask this to everyone. There is a thought out there that someone who uses the physical keyboard a lot tends to find that the keys "bubble" hence making it seem as though they are less flat that before. The topic was brought up because someone got a refurb and thought they keyboard was not the same as the first Droid they had. Now, I NEVER use the physical keyboard and after reading the post I checked mine out, indeed the keys seem more "raised" than before. I belive it may be the heat generated from the device over time that causes a change.... Any ideas?
