There is not a significant jump in quality over regular DVD or other high-def mediums including direct download, digital cable, etc. The players are still too expensive. The support for both formats still a bit lacking. The technology of both formats still not 100% standardized. No 100% clear winner yet so you may end up with obsolete technology if you pick the wrong one (though it's starting to become a bit lopsided)
Perfectly content to wait. My regular DVD collection is extensive and works fine.
