How far apart in quality is 1080i vs. 1080p?


Just wondering if I should stick with my upsampling Sony recorder or purchase a PS3 or true BlueRay Player.

The difference between either Blu-ray and HD DVD and upsampled SD DVD's is huge, especially on larger sets. I run the 70" XBR and @ 12 ft there is no comparison, friends use 55" sets and say the same.

As for the PS3, I own one as well as several other Blu-ray players, the PS3 is a cool game, but a mediocre Blu-ray player. If you want a true player, buy one of the stand alones.
1080i is usually standard def (480p) upsampled. 1080p via a Blu-Ray/HD DVD player is true HD
I love the PS3 and it has superb Blu Ray playback. It has the fastest load time of all models, either stand alone or PS3 game and Blu Ray player.
