you know, i thought about getting the 2x too, but then went for the Nexus S, which ist a very nice piece of kit.
the optimus 2x will suffer from two very important things:
1. being the first:
as i understood a lot of people, the tegra 2 seems a little rushed, to be on the market as firstly as possible, leaving to be desired, in comparison to other dual-core chipsets.
apart from that, hell, it's dual core and will start to shine with ice cream sandwich, when it comes. it has those annoying bugs, reboots and stuff, which can be fixed with a custom rom,
but how many owners will really install a rom themselves?
for us tech-nerds: root that thing ---> CWM ---> Custom Rom -->
for everyone else: "damn, why does it reboot all the time, why does this not work? that thing sucks!!" --->
2. the terrible screen:
it's not technically bad, but rather the build quality is, again, rushed. don't know whether you noticed, but i almost died of eye-cancer on the behalf of this.
the screen bleed in the corners of the screen. try it with a very black background and ADVERTISING SPAM light flow onto the screen from the holes in the corners of the display.
you won't notice in bright pics, but when there is black, you will see.
this is not about the 2x though, rather about it's price, which is so cheap, because it can't really keep up with the up and coming dual-core phones and they very well know the problems
want to sell those off, before the start rotting on the shelves... tegra2 was just an intermediate step on the way of the phone.
that's where the OMC enters the story, as i has to compete with such a phone about your money. you think, that it's not much of a deal, i agree perfectly.
ZTE are upcoming, which means, they try to come UP. in doing so, of course, they try to maximize their profit, to invest furthermore into more products, build quality, software, whatever. as mentioned before, they try to get you into buying that thing for the huge screen and an adequate working speed. if it works, let them have their piece of the cake, maybe they can succeed.
after some research and consideration, i went with nexus s for google software reasons and for the top notch hardware build by samsung, i can be sure, there won't be much chance for miss here. in their respect they both know best.(and that this black beauty just looks dead-sexy
imagine it as it is with bands: the first album is to win the fans for you, the second is to keep the fans, the third is to show, that you are really good
the second album hasn't got to be better compared to the first, but has to hit the demand of many.
p.s.: the Nexus has both the USB and the Audio Plug at the bottom of the chassis
