I'm headed out to pick up a new TV. I've settled on the Sony KV-40XBR800 ($2500). However, I found a guy who has the KV-40XBR700 (last years model) for about $1300 less. Trouble is, I did a feature compare and it seems to be that there are very few obvious differences between the 2 sets (DVI input and Sony Memory Stick port on the KV-40XBR800), problem I'm having is deciphering the changes in the names of some of the other features. Bottom line, I need to know if the Specs of these 2 sets are comparable aside from the DVI and momory Stick deal. Help
