.......and here I was wanting to really like the SG III since I already had the orig Atrix 4G & the Atrix 2 (which I love) but wanted something different. Because of my eyes (I guess), I just could not get used to the screen. It appeared dull & bluish to me & simply was not bright enough even at the brightest setting & the HTC One X did not have a card slot. So decided to stay with the Motorola line as their phones are pretty sturdy & got the Atrix HD. The screen just pops to me & is quite bright at even just 1/4 - 1/2 of the bright display setting.
My WiFi is rock solid (just like my other Atrixes) & since I'm not a very heavy phone user, the battery lasts me for several days. Only time will tell if this phone is a keeper. Since I'm still within the 30 day return period, still have the return option. The HTC One X was my second choice even without the SD slot.
To help with the battery life, I always turn off the screen (sleep) whenever I'm done using the phone & since the screen is so bright, have it turned down. My phone useage is mostly indoors, thereby the screen is not giving off a washed out look.
