What if any 1080p gear do you own?
Sharp 46" LCD TV, iSync Pro video processor. Costco had the Sharp on sale such that the price was comparable to 720p LCD TV's at other local stores.
Is 1080p alone enough of a reason to upgrade your current non-1080p equipment?
No, because ...
If you have seen 1080p content did you really notice an improvement over 720p and 1080i?
No, I can't really tell the difference between 720p and 1080p. The local Microcenter had two 46" Sony LCD TV's next to each other. One was the 720p model, the other was the 1080p model. About the only difference I could see between them was the price. Ditto with the local CompUSA and two 46" Samsung LCD TV's. If I squint really hard at certain parts of the image, I can kinda sorta maybe imagine that I see a difference between them. But since I don't watch TV by focusing on only a certain part of the image to see how pixelated it looks, the two resolutions are essentially identical to me.
