I'm not too happy with Motorola right now to be honest. The atrix is my first Motorola product, and while I love it dearly, it has some issues (although most electronics do these days). I bought one around the 2nd day it first came out, and it was great except that I had to get that one replaced before my 30 days with AT&T were up, due to it severely overheating (to the point of almost burning me inside my pocket while it was just idling with nothing up but Handcent). Got that replaced pronto, and this 2nd atrix has never had that issue. However, well past my 30 days now, this atrix one day randomly rebooted, which normally wouldn't be an issue (that happens to smartphones all the time. No matter the platform. Happened a bit on my Bold 9000 from RIM years back too). But usually it's no big deal, just a little irritating - it restarts and everything is fine. Well, this time, my phone rebooted itself while I was using it, and when it came back on, it decided to never load past the red "M" dual core motorola logo, and instead issue me an error in white text at the top. Needless to say, it never came back, and I was forced to (with the help of the fine people of this forum) completely reset everything by hooking it up to my PC and flashing it back to the sbf file. That sucked, not only because it just plain sucked, but because I did absolutely nothing to cause that. People might say "well if you root things may go wrong", no, I wasn't rooted, I was nothing but stock. I didn't even tempt the devil, yet it still happened to me, for apparently no reason at all. Thank the lord for the internet, without it I would've had to ship my phone to Motorola themselves for a "fix" or a "replacement", dunno which.
The Atrix has some known issues you MUST look out for when you buy yours (if you do): Probably #1 on the list would be the "muffled voice" issue, which is huge, and affects a lot of handsets. What happens is when you're on a call with someone, that person can not hear you properly/clearly, and it usually gets worse as the days go on. Some have reported that it got so bad, their voice was basically just a sound to someone else, completely incomprehensible.
Definitely be on a watch for that, it can render your phone without its main purpose - making/receiving calls.
The atrix is known to have colors appear closer to the yellow side of the spectrum. For some users the fingerprint scanner doesn't work properly - I had issues before, but when motorola released a software update, my problems went away (though some other people still claim to have issues with it). The atrix does get rather hot towards the bottom left (or was it right?) side of the phone. It shouldn't get to the point of almost burning you, though, so be careful of that. Nevertheless, it does get warmer than most other phones, possibly due to its dual-core processor, but I've no idea. It's just another known fact. It's not usually a problem though, and it's mainly only hot when I'm playing a graphics-intensive game such as the ones found in the Tegra Zone.
Another HUGE thing, which irritates the CRAP out of me, is the atrix loses connectivity very frequently. When it does, it finds it again pretty quickly, but if you're in the middle of an online game such as playing Dungeon defenders online, consider your game COMPLETELY RUINED. I am getting SO sick of this. Once the connection is lost, the phone seems incapable of immediately picking up where it left off (it only take a half-second of lost connectivity), and the game will come crashing down, everyone being kicked out at any second. This is mainly the biggest issue if you're playing a game online, but you can also visibly see the issue with less dire effects if you just open the Android Market from the phone. Usually, it will immediately pop up & tell you you need to hit "Retry" because you have no connection (even though you really do, according to your status bar). Sometimes you have to hit "retry" two or three times in a ROW to get the market to finally load. Some people have reported hitting retry up to nine times in a row before it showing, though I've never experienced it to be that horrid. It is nothing major, just irritating. You can also sometimes see this when loading up the browser (or a 3rd party browser such as Dolphin, too). It will ask you to hit retry, and then afterwards, it usually loads right up.
The reason I'm going into such detail is so you have all the facts and can best determine what to do for yourself. Because, while this only one random anonymous guy-over-the-internet's case, my older brother just got a motorola Xoom tablet about a month ago now...
He is getting super frustrated with it, for a lot of various reasons. I feel bad for him, because it's his first android experience and he doesn't know whether to blame this stuff on Google or on Motorola.
The reason I'm getting wary of Motorola products myself is that his Xoom is experiencing very similar issues that I am experiencing with my Atrix...particularly the loss-connectivity thing. Although his seems to be worse - sometimes he has to hit retry when trying to load the market or browser up to 10 or more times...it gets worse, when he attempts to download an app from the market, sometimes it hangs FOREVER at "Downloading", never even getting to the installing part. He could wait 20 mins and it never does anything. Sometimes hitting the back button to load a different page gets the download to begin, but even that doesn't always work, because when he goes back in, the download cancels itself. He is getting pretty frustrated. Yes, btw, we both have perfectly working wifi routers with great connections to it, if anyone wants to know.
Honestly, I can't tell you what to choose, but my next android phone will not be from Motorola, it's looking like. I'm not very happy anymore. If I hadn't extended my contract for another 2 years with the atrix and could somehow get a new smartphone for the upgrade price without being eligible, I'd be selling my slightly used but in great condition atrix to somebody (along with the HD Multimedia dock) and getting a different android phone on AT&T. :-\ It's up to you, though.
You say the phone looks so shiny, but, trust me, ALL new phones you see will look shiny & fanatstic

Check out that Samsung Infuse..daaamn!
