I've had the Atrix for 24 days now after leaving my BB in the dust. No regrets there. What I love about the Atrix is the screen size and resolution. It completely buries the BB in that regard. -Completely-. I really enjoy all the incredibly useful apps available. It is a bit of a chore finding the ones that work for me personally, but at least they're there. There are no apps for the BB. Email is syncing just fine (all 5 of them), though I'm having problems getting my business email. The speaker is awesome, far better than it was on my BB Bold 9000. I don't play games, or use my phone for entertainment purposes but, I did try a free game on it and it was a real treat. Social networking on the Atrix beats the BB hands down. This phone is made for social networking. I really enjoy having several desktop screens I can customize with widgets. This is probably the best part of owning an Android phone for me. I have 4 screens, each with their own purpose. It makes quick work accessing what I want, when I want, without having to go hunting for things. For me anyway, this interface beats the BB hands down.
I still cringe a little every time I have to type something. Going from my beloved BB physical keyboard to a virtual keyboard was definitely culture shock. I'm getting used to the keyboard, but it is slow going. No more typing by feel. I have to be very deliberate and delicate when selecting the keys. I do far better using one finger than I do, both thumbs. I still hit all sorts of things on the phone, but not as often as I used to. The touchscreen buttons on the bottom of the phone are especially problematic for me. In the middle of typing an email, I inadvertently touch the home screen button, or back button, losing my email in the process. Well, it's still there, I just have to go find it. The keyboard is not wide enough for me and no, I don't have fat or big fingers. I'm female, 5'7" and I do not have fat fingers

I guess I'm just virtual keyboard challenged. I would expect that after 5 years on a BB. The Atrix is not wide enough to use a wider keyboard, at least wide enough for me. This keyboard thing is still not enough to cause me to go back to RIM and their broken, substandard phones, but I must say, I really don't enjoy typing on the Atrix. I find myself putting off answering longer emails until I get home to my laptop.
As of 2 days ago, people started complaining that I sounded as if I was 1000 miles away in a tunnel behind a brick wall. No complaints at all until the 22nd day of ownership. I've read about sound quality issues with the Atrix but, since I hadn't experienced it, I thought I was one of the lucky ones. I guess not. Since the sound issue seems to degrade over time, this is a deal breaker for me.
Since getting the Atrix, I've had routine dropped calls. I rarely had dropped calls with my BB but, at first, I thought it just might be the network. Now, after 24 days, with the dropped call issue getting worse, I'm guessing it's the phone. Still, dropping a call 5 times during a conversation is/was intolerable. If it was in one particular area, I'd know it was the network, but it's not. I was in a doctors office the other day and I was unable to place a call out. I had to step outside the building to make a call and even then, I had to find the right spot in the parking lot for the other person to be able to hear me. I've been in this doctor's office before, but with my BB and never had a problem placing a call. This makes me think it's the phone. Above everything else, I need a reliable phone.
Copying, cutting and pasting on the Atrix is pretty frustrating, for me anyway. It's a different process for each app. Copying text in an email on the BB was simple. On the Atrix, using the Gmail app (don't like motoblur) I have to select options, then More, then Select Text. Then, if the text I want to copy is out of screen view, I can't copy it in one action and there is no option to copy the entire email either. Now again, that's with the Gmail app, but I didn't find it any easier when testing several other email apps. If one app makes it possible to copy the entire email or web page, at the same time, it doesn't do something else I need it to do like, select multiple emails at the same time. I don't know if this is an Android thing, or an Atrix thing, but it makes this simple task far more difficult and time consuming than I think it should be, at least for me. I realize this isn't a "Business Phone", but I do think copying, cutting and pasting should be a standard in any operating system.
All of a sudden, I can't access my bank account through the app. The latest update seems to have killed that on the phone. Since I use that every day, this is a serious problem for me.
Though I haven't loaded many apps on my phone, it's been intermittently, completely non-responsive, or maybe I should say lagging. Nothing on it works for 10-15 seconds. I know that's a short time, but being in the middle of something and having to wait for the phone to respond makes that 10-15 seconds seem like minutes. Now I could have caused this to happen somehow, so I can't say this is an Atrix thing, but it is a bit frustrating, none-the-less.
I thought I figured out why the battery wasn't lasting very long, 5 hours on a good day. I turned off wifi which was connecting on its own automatically. Well, as it turned out, after a full night's charge, the next day, the phone was at 15% after 5 hours of moderate talking. I exchanged the battery, cycled it yesterday, but today, battery is still draining dramatically. This is after auto-killing all but 17 apps I use every day. Still, this could be a noob affliction since I'm not nearly as competent with the phone as other, more experienced users.
I also have a problem video conferencing with my clients. Oddly, many companies have gone the way of the iPhone. The clients I talk to don't like it, but they're stuck with it. Unfortunately, I can't video conference with anyone on an iPhone. They use Skype and Skype is not available for the Atrix and my clients can't download other apps due to the network security policies imposed by their companies. This is a deal-breaker for me. I must be able to video conference for my work.
Now I'll get a little silly. Every time the screen times out, it locks. In order to use the phone again, I have to swipe the unlock tab to the right but first, I have to press the physical power button at the top back of the phone to wake it up. This is more of an annoyance than anything. On the BB I locked it if I wanted it locked. If I didn't, it was ready to go with one tap of the keyboard.
Speaking only for me, the Atrix is an awesome phone. In fact, it's so awesome, that I will never go back to BB. That said, it's not a productivity phone, at least for me. What you can do in one click on a BB, is 2-3 clicks or more on the Atrix. I know Motorola is going to add more productivity features to the phone and, I'd be more than willing to wait for those improvements, were it not for the issues I mentioned above and its counter productive nature. To be honest, I think this phone just offers more than I need. I'm not a tinkerer. I don't play games, watch a lot of movies, or need fancy 3d or live wallpapers. I don't even need the highest resolution screen. I just want the phone to be fast and to help me be more productive. I don't need the phone to be a computer. I have a netbook for that and my netbook cost less than the dock Motorola sells for the Atrix.
So, overall, despite the issues, I love this phone and I'm still so very happy not to have to deal with a broken, antiquated, limited Blackberry. The apps, the screen, well, it's just a very sexy, great to hold, great to customize phone. For all you BB users out there thinking about dumping your antiquated Blackberry, Android phones are the way to go. They are far better equipped to handle anything you throw at them. They seem to be updated more and the updates don't seem to be the tiny incremental updates RIM doles out. My advice? Move into the future. Move to Android and leave RIM where it belongs; in the past. You just have to find the right Android phone for you.
Sorry for the length of this behemoth post and, I hope I didn't offend anyone. I was just trying to relate my experience with the Atrix but, if I said anything that upsets anyone, please accept my apologies in advance. I do credit some of the issues I'm experiencing to my lack of experience with the phone. That must be considered when reading my post.
