Just as many people (I would think) dislike Windows Mobile as dislike the iPhone. Just as there are many people who dislike Symbian, Andriod, Blackberry, etc.
One thing I have to admit though, is that the iPhone definitely raised the bar for everyone. Out of the box, it was fairly easy to operate and the safari mobile web-browser was done extremely well.
The entry of Apple into the mobile market was great for the consumers. We now have more choices and
BETTER choices than ever before!
