No way.....not now that I've experience android. If I never owned an android, I would probably take the iphone. Now that I HAVE a DINC, I would never switch. I will hold on to this Dinc until something blows it out of the water (or I brick it from playing around too much). BEST phone I've ever had. There is nothing the iphone does except auto sync with itunes that my droid can't do. Personally, I've always been a big fan of Apple. I only use a MAC, except at work where I'm forced to use an outdated PC. I would still pick a ipad over a tablet (although I own neither because there is no practical use for it). Even when I do decide to get an ipad, I can buy the wifi only for much less, and tether to my DINC for free. Try that with an iphone. Also the free turn by turn navigation. Sure, with an iphone you can pay garmin $40 for the same feature but don't hold your breath for any map updates.
Personally, I hate the Iphone OS, all the phone is is one big app drawer that you can switch around the icons. If I can't customize the way I want it, I will hate it. No doubt it's got its own awesomeness, but I'll take my Dinc any day of the week and twice on sunday. The only plus the iphone has is better battery life. Until I can change my own battery, and add my own memory card, I won't take an iphone.
