In other news, some people don't know what a full OS is.
First, you said "real OS" not "full OS". Second, the iPhone OS is real and full. Just because it has different features than what you hoped for does not change that fact.
Oh, and it's not mantra. Just reality. An attachable keyboard and $10 "word processing" apps don't change that.
It's just something that is repeated without any thought or meaning because it sounds like an insult. When you heard Apple was going to come out with a touchscreen computer without a keyboard, was it really a surprise that was similar in shape to an iPod touch? Were you expecting it to look like banana?
