Dear god, am rolling my eyes so hard right now.. lol, who the heck cares if a person is walking around with an iPad or bluetooth headset?
Sheesh, if a guy decides to fasten his iPad to his nostril and allows it to swing like a pendulum, I am not going to lose a night's sleep over it.
Now let's put things into perspective : which seems more silly? A person sitting in a cafe minding his own business while completing an important project on his iPad, or a person who comes online to whine about how people with bluetooth headsets and iPads in public hurt their souls?
And to the OP, I know exactly how you feel, I have seen a few posts like this on here, I even saw one 2 days ago, and the comment was so irrelevant to the main topic.
Anyhow, I own neither bluetooth headset or iPad (at the moment) but believe me, there are more things in life to worry about than waste time with folly. 😉
