Do you remember what everybody’s pet-peeve was when cell phones first came out?
Pocket-dialing–when somebody accidentally dials the last person they called while their phone is in their pocket. They don’t know they did it so the person on the receiving end fruitlessly repeats “Hello? Hello?” and then finally gives up. Somehow, engineers and cell phone users have adapted, and the pocket-dial is virtually extinct.
There has been a lot of deserved praise for the Apple iPhone. It’s a really slick device, and it has pioneered a lot of great usability improvements. However, they haven’t fixed the longest-standing usability issue. My roommate just pocket-dialed me from his iPhone.

good post.
However, I’m a shareholder, so I think everyone should go out and buy two.
