They ARE in a class by themselves.
No other smartphone can match the iPhone in terms of popularity and sales. Many have tried and they've all failed. Quarter after quarter, year after year, the iPhone (whichever is the newest one) is ALWAYS the best selling smartphone in the world.[/B
That would give me cause to be arrogant if I were them. And really, they are the only game in town if you prefer iOS. So from that standpoint there is no competition.
Some people put OS lower than other metrics, but a good amount of people don't. If you prefer Android, you aren't buying an iPhone anyhow. If you're an iOS person, all these things that Android "has had for years" (which I completely disagree with - implementation is a HUGE component of a feature) don't matter because a phone with iOS didn't have them.
