When I purchased an ipod touch a few years back, I remember having an issue with so much functionality being put through a single button, a sure design flaw I felt at the time since pressing one button repeatedly would lead to it breaking quickly. When I got the ipad, i was pleased that they had added "gestures," so that between that and a smart cover, you could use the ipad for years and never even touch the home button. Now that i just got an iphone 4s this week, it appears that only the home button can bring you back to the main screen, so it seems like apple has not moved past this basic flaw. If I was a conspiracist, I'd believe that apple had built-in / planned for people to break these devices' home buttons after a certain amount of time, compelling expensive repairs or complete upgrades. On the iphone, is there an alternative method to using the home button?
