I also have a video going through my G2X and discussing some of the pros and cons of new devices coming out I would appreciate your time in reviewing the video and commenting with your thoughts and suggestions :-) http://www.youtube.com/watch?v=oBwwa5Q7veE
Stay away from it unless you are ready to root and flash different ROMs. LG has pretty much abandoned the G2x and T-Mobile is about to launch it's new flagship.
BTW, I plan on buying the Samsung Galaxy S II after about 1 month from when it comes out (want to read if there will be many horror stories. Mind you, there always are but I gauge the quality by the number of complainers ;-)
As a FYI, I have a rooted G2x which is running CyanogenMOD 7 nb154 (GB 2.3.7) and it's OK. Without CM7 (or other cooked ROMs) this phone is sub-par for a "flagship super phone".
