Today I received my package with LG Optimus 2X, which I have ordered from 4launch.nl - I recommend them for great support and fast delivery!
And now about the device:
The hardware feels great, the quality of materials used is very hihg, the O2X feels very solid in hand. The IPS display, covered with curved Gorilla Glass is very bright, and I don't miss AMOLED fom SGS at all.
The stock LG Launcher isn't the fastest one, but once you replace with ADW or Launcher Pro it is balzing fast.
Overall the device is very responsive.
Now I'm going to root it, install CWM recovery, and try some fun with custom ROMs.
