[Atrix 4G General] maledyris:
I'm also coming from an iPhone, and here are some things I think are superior on the Atrix (and Android) to the iPhone (and iOS):

1. Non-intrusive notifications! I hated how on the iPhone, notifications pop up as dialogs that have to be closed. Sometimes you're doing something important, and you get a text message which pops up right in the middle of the screen. Irritating! I like how you can slide down the top bar when you want and it shows you your notifications.

2. Notification LED. It's great to be able to tell that you have messages or a missed call without having to turn on the screen.

3. Four hardware buttons instead of just one. After you've used the phone awhile, you'll realize how useful a back button and a menu button can be. You have to switch back to home less than you do with an iPhone. Also, hold down your home button and shortcuts to your last 8 used apps will appear.

4. Every application must advertise what features of your phone it has access to in the Manage Applications settings pages. So if an app can read and write to your contact data, it says so in the settings. On the iPhone, you have to rely on Apple to make sure all apps are doing what they're supposed to. Worse, if you get apps from Cydia, well then you're completely on your own.

5. You have 15 minutes to get a refund if you buy something from the Android Market. That's a pretty short time if you have to download a big application, but better that than no refunds at all.

6. Having the option to use an external micro-SD card is pretty nice.

7. Unlike the iPhone, the home screen and the app drawer are two separate things. It's nice to have widgets to customize your home screens.

8. For obvious reasons, Android versions of Google applications tend to have more features on Android than on the iPhone. For example, Maps has that cool 3D compass view, instead of the regular "up is North" top-down view. It also has a Street View add-on which is pretty neat and works quite well.

9. GPS seems faster and more precise on my Atrix than on my iPhone (and my friend's iPhone 4). I've heard others say the opposite with respect to the iPhone 4, so maybe it depends on where in the world you are.

10. For Bell users (ATT users have to pay I think?), Mobile wifi hotspot works great. I've tried tethering my Macbook Pro to the phone via wifi, and it works really well.

11. There's a basic data counter built in, which shows you how much data you're using, and by which apps.

12. There's a pretty decent Battery Manager built in, which shows very clearly what percentage of your used battery was used by each phone function, or application.

13. It comes with Swype as an alternate input system to the virtual keyboard, but you're free to install other 3rd party input methods if you like (there are quite a few).

Well, I don't know if I missed anything, but for the most part, these are the things that impressed me the most after using the Atrix for a couple weeks. I'm very happy I moved to the Atrix, but that's not to say that I hate the iPhone. I still like it, it has a very polished feel and the best screen in the business. And after all, it was the breakthrough smart phone when it first came out. There are just a few things that I think they really need to improve (notifications!).
