you are incorrect... rooting is not required to get apps that aren't in the market. i am not rooted and have quite a few apps that i didn't get from the market.
i was close to getting the nexus s, but realized i was only going to get it because of the screen. aside from that, i wasn't gonna get the dual-core processors. i wasn't gonna get the 1gb ram. i wasn't gonna get the front facing camera. i wasn't gonna get the media dock and/or webtop capabilities. nexus s seems a bit outdated, imho.
i have yet to own an HTC device with great battery life and screen responsiveness. i have owned/used a lot. evo, nexus one, tilt, 8525, 8125, etc. not saying it won't be a good device, but if you want good battery life and great screen responsiveness, HTC isn't gonna be the best in that category.
First off, The Nexus S has a front camera lol.
Dual core means nothing in Android right now since no apps actually utilize them fully. Outdated? no, the Nexus S has a better camera, and still keeps up with the Atrix even with it's single core.
Screen responsiveness and you own a phone with moto blur? LOL you have to be kidding moto blur is by far the worst (right next to touch wiz) UI on android, sense, by far is the best, widgets are top notch, and with 2.1/2.2 sense it has a bunch of customization (check out the thunderbolt).
I agree HTC doesn't have amazing battery life, but no android phone is top notch in battery life, maybe Samsung, they have impressed me the most with battery life. Like I said I get 9-12 hours with medium to heavy usage (100% brightness as well).
Yeah spend $500 on that stupid webtop, I'd rather buy an actual laptop then buy that thing, yeah cool idea but not for $500 EXTRA.
Unless your running half of your apps on your phone you don't need the 1gb lol hell my evo has 512 and I can't make my phone freeze if I wanted, I can run 15 apps and no problem (oc'd to 1.2). Yea more more ram the better but yeah i agree 512 in the nexus s is pretty ****ty for a new phone, but I've played with the GSM version and it kept up with everything I threw at it, plus it's going to get updates straight from google and it won't have a bunch of crapware (not sure what comes on the atrix).
Of course being in the Atrix forum everyone is going to think their phone is the **** and has no problems at all.
