The issue is cultural relevance, product wise. It has never been a stunning product. The original looked like a calculator. The original was a hit because there were literally no viable competitors at the time. It served a functional purpose. As soon as there were competitors that could do some of the same things (connect to secure exchange servers), it was a battle. They were skipped over, and now they are catching up (5 years later) rather than trying to skip over the competition.
