I have an iPhone and an Android phone. The HTC EVO is a solid phone, but pales in comparison to the iPhone. The notifications are the best thing about. But at the end of the day, it is a sleeker palm type device. That is the feeling when I go in to the main sections of apps and settings. It is just like the old Palm OS. I hacked it so I could tether the phone, and used it for client calls and texts. How many apps do you really use? Look at it this way, the apps that I use for my iPad 2 (and used them on my original iPad) I used every day for work and play (I am a poet, no?). There is nothing like penultimate, pages, iMovie, Garageband, numbers, fastcase and so on. Android could match the sheer number of apps and still not be as solid as the iOS apps.
Although iOS itself has not been revolutionized over the last four years, I agree with another post about having buyer's remorse once a year. I used to use the Sony Palm Pilots. Seriously, those bastards upgraded a device less than a month after the one I bought was released. No customer loyalty. No patience with the devices they release so they need to ship out a new and improved model before even synced yours with your computer.
