Watching the iPhone commercial showing off YouTube, I noticed this:
I had my cell phone by me and I realize that the Answer button was on the other side of the phone. Most recent phones follow that standard. A quick look at The New AT&T's offerings confirms this. Blackberry, Motorola, Nokia, and Samsung all seem to use this standard. So why didn't Apple make their interface like everyone else's? Probably either lack of experience in making cell phones, accessability by the right hand, or just Apple thinking different--err, -ly.
Some things never change.
