The first time I played with this phone I wasn't impressed either. I thought the screen looked dull and not bright at all. Oddly enough I found the same thing on the Inspire. I couldn't understand why everyone was liking these screens so much.
So today I checked them both out again, looked under the settings and found on both phones the brightness of the screen was turned down to 3/4. WTH? Why would these stores do this? It's not like it affects battery life since they have them on chragers.
So I turned up the brightness on both demos and WOW both the Inspire
and the Atrix have gorgeous screens. Now I can't decide again.
The size of the Atrix and the overall feel of the phone is way more appealing to me then that huge Inspire but I like Sense a lot (Motoblur is lame but not too terribly offensive) and I find it easier to type on HTC phones. So if I get the Atrix I'll probably download launcherpro and a better virtual keyboard.
That's been my experience so far.
