People just dont realize how important this is. Right now my iphone 4 is being repaired because my home button started to fail after just one year! The home button on the iphone 4 and 4s is really bad designed. Considering how important this button is to exit apps and to multitask I dont understand why Apple has not implemented the capacitive button yet. Fortunately it seems they will on the iphone 5, based on the rumors. Android has had capacitive buttons for years. It really does improve the usability of the phone and, especially, it extends the life of the phone, since its not that likely that a capacitive button will fail as often as a hardware button. Many people have problems with the home button on the iphone. I wanted to keep my iphone 4 for at least 2 more years, since Im really happy with it, but I didnt expect to have to send it to repair just one year later after buying it. Im pretty sure with a capacitive button and good care I would never have had to send my iphone to repair. Really wish Apple had included one on the 4s... Praying they will on the 5.
