Just out of curiosity, have you downloaded android OS, modified it and installed it on your incredible? What have you done on your incredible that can't be done on the iPhone due to it being open? Not trying to flame here, Im just curious...
Not the original poster, but I'll offer my story. A couple of days ago, I got an unsigned non-Market app (actually it is on the Market, just not in my territory) via email. Signed it myself using free tools and installed it on the phone. As far as I know, can't be done on iPhone. Also, as I use multiple computers, on any of them I can, using standard USB cable and OS file management, access any file (music/video/apps/whatever) on the phone. And copy anything from the computer to the phone, and use it on the phone. Unlike with iPhone, no extra software necessary, no warranties voided, not subject to approval by 3rd party.
Also, I'm about to start development of an application for Android. No code exists yet, and already I know my app can be published. I couldn't be sure with the iPhone. Google may reject the app from the Android Market, but I can still put it up on the web and have people be able to install and run it. Furthermore, I have a sizable amout of development investment in Adobe Flash. As of this summer (June or so) I will be able to leverage that existing codebase and development process to make Android apps. That just won't happen on iPhone.
I guess the last two things don't mean much to you if you're not a developer, but at least living without market lockdown and file lockdown is something that should be appealing to anyone.
