... and if you're, "an informed consumer", then you would probably know what you want before getting the phone which means you won't likely return something that you don't like.
If you're really that informed, you can play with them in the store comparing the differences yourself side-by-side (being already well informed about what those differences are).
OTOH I know EXACTLY where you're coming from. I have two phones, an HTC HD7 (Windows Phone 7) and an HTC Amaze (Android). Android is fun to play with but productivity is SEVERELY reduced by the inefficient disjointed nature of the beast. It's a resource pig, and totally lacks integration. A jumble of apps lacking a cohering vision.
e.g. someone sends me a text. I read it and need to call them to reply. Can I just tap the contact name at the top of the thread? Nope. I have to go home, go into contacts app, search for the name and tap call (or do about the same after entering the phone app from home). What kind of crap is that? ... I show my droid toting friends stuff like this and they say oh cool! and go back to their ignorant sheepish existence happy with their toys, while I tote a tool. Sure, there's vlingo and voice dial and the like, but it's unusably inaccurate... just another toy. TellMe works a tolerable/usable 90% of the time, and it's only going to get better.
