I'm very disappointed by this:
- Design is awful - this is the ugliest mainstream smartphone I've seen in years
- Nature UX looks worse than TouchWiz 4.0, has a stupid name
- The new features seem to be complete gimmicks that would never be useful
- It's ugly
- It "tracks your every move", "follows you around", and "waits until you sleep"
Those are the bad points, and there aren't really many good ones. It has lots of storage, and we'll have to wait and see about the Exynos Quad to see if it outperforms the Tegra 3 and Snapdragon S4. It has a big battery, but that doesn't mean anything if it turns out that the SoC is super power hungry.
The rear camera is probably going to be just a little better than the S2's, with zero shutter lag, and nobody uses the front camera anyway. Connectivity hasn't added anything from other phones besides Bluetooth 4.0 which hasn't been seen a lot before.
But at the end of the day, a lot of people will take one look at this phone and decide that it's too ugly to buy.
As Josh Topolsky said like 15 minutes ago on The Vergecast, I honestly have no desire to own this device.
