Price is the disadvantage to a 1080p display. For some this won't matter. However, for many it will. I spent $1900 on a Pioneer 5080 (768p) that would completely trounce the PQ of any 50" 1080p TV at that price at the time. The 5080 has an excellent scaler, so 1080i and 1080p sources look incredible. I sit 9 feet from the screen and see no pixelation, SDE, etc.
Resolution isn't everything. ISF (Imaging Science Foundation) claims that contrast ratio, color saturation, and color accuracy are all more important to PQ than resolution, which is fourth on their list.
The two reasons for
needing 1080p are computer usage and close viewing distance. I had neither of these issues, so I decided to get a 768p with better PQ than a 1080p with a worse PQ at the same price. Of course, I could've spent $3500 for the Pioneer 5010 and had the best of both worlds, but I would've likely seen little to no difference, definitely not $1600 worth of difference.
Using
this viewing-distance chart as a guide, the benefits of 1080p over 720p become noticeable at distances closer than 10' to a 50" screen. YMMV because some people notice the difference closer and some farther. I can sit at my side seating 6-7 feet from my TV and just barely start to notice the limitations of 768p. Some (very few) can notice the limitations at farther than 10 feet away.
If money is no object, then by all means buy the absolute best 1080p TV out there. However, there is likely a limit to what you want to spend on a TV. That limit, the size of TV you want, your viewing distance, and whether a computer will be connected to it will help us to guide you to the best decision (in our individual opinions).
I will put as a disclaimer that I haven't at all kept up with the TV market since I bought mine last December (that makes it easier to be totally pleased with my TV and not want the newest, latest, greatest thing). Even at that time the market was making a big shift to 1080p, so you might not be able to find many quality 768p sets these days.
