I've had my Bionic since Day 1 as well, and 902 significanly improved 4G.
Overall, I think my Bionic has been amazing. Battery life is excellent (although slightly shorter now with 902), speed/responsiveness is great, stock camera is excellent with updates (also use HDR+), call quality is great, wonderful assortment of accessories, and the screen is the best (for me) balance of color, sharpness and usability indoors and outdoors. Stability is rock-solid. I freak'in love this this thing and it's going on 6 months old already!!
I am VERY happy with my Bionic choice. Happier than with my beloved D1!
