Well if you like noise cancelling microphones then the only mobile phone on the planet with any kind of good noise cancellation is the Nexus One. There are some demos around online which show calls made from a noisy environment with a Nexus One and another random phone. It's quite impressive - reasonably clear on the N1 versus illegible on the other phone.
People like different things, but if you look at this article - http://extorian.co.uk/blog/?p=31 - you'll see the graph shows how Android is quickly becoming the mobile OS of choice, whereas other mobile OSes are losing popularity - the iPhone had a scary drop in popularity. This says a lot about Android. It's the OS people want on their new phone.
What do I like about Android? Well, as many will tell you, the iPhone is very easy to use, and it just works. That's great, but if you think about it that restricts what you can do, and it's kinda like having a baby's toy. With Android it's highly configurable. You can set it up exactly how you like it, and you can drill down into some very advanced stuff. I've had my G1 over a year now, and I still keep discovering new stuff I can do on it every week or so.
Android also has Adobe Flash, and Firefox (soon). The iPhone doesn't, and likely never will if you have been keeping up with Apple's policy changes in the last few days (that actually goes as far as prohibiting the use of Flash in favour of HTML5 on the iPhone OS 4). And really that's the big thing for me. More and more big developers (Adobe, Mozilla, etc) are stating that Apple is too restrictive and dictatorial, whereas Android isn't. As Android eats more and more into the iPhone market share, it will eventually (predicted 2 years) be the most common phone OS. The most common phone OS at any given time is well supported. For example my bank has an app for the iPhone, but not for Android. So when the most common phone OS eventually becomes Android, and take into account what I said above about big developers dropping the iPhone, there will be far less incentive for companies to support the iPhone. When that happens, the situation may well reverse and you'll find apps for Android everywhere, and less support for the iPhone, especially when you consider how restrictive development on the iPhone is. That will probably cause even more people to migrate.
Of course, there will always be iSheep, but I'd like to think common sense will prevail. I mean the HTC Desire is almost identical to the Nexus One. I did a comparison of the HTC Desire and iPhone 3GS (http://extorian.co.uk/blog/?p=101). I think the results are blindingly obvious, yet a friend of mine with an iPhone insists the iPhone is still the better phone. He hadn't even heard of the HTC Desire 5 seconds before he made that statement - and that, my friend, is the power of Apple brainwashing in action.
