I fancied changing my 4 year old Panasonic 50" PX600 (great tv in its right) and had initially looked at the Panasonic 50" G20 plasma. However, upon closer examination, I didn't like the look of the G20 despite it being a very technically competent TV.
I didn't want to go down the 3D route and hence came to the conclusion that the V20 would be perfect for me. The TV is very aesthically pleasing to the eye; unusual gun metal finish as opposed to a lot of blacks used by many TV manufacturers. In addition, it had all the features I wanted above my trusty PX600 (full HD, faster frame rate, more HDMI sockets, wi-fi capability...)
Picture wise, SKY HD / Freeview HD looks gorgeous, Movies via blu ray look smooth and colours vivid. Motion is handled with ease.
Sound wise, I think the speakers are ok and do the job admirably.
All in all, I am 100% happy with my purchase.
