For me, while I have a HDTV (32" 720p, definitely not the latest and greatest) and a Blu-Ray player (okay, it's a PS3), I have only bought two Blu-Ray discs. What has been stopping me--besides the fact that I buy very little physical media these days--is that my audio equipment doesn't work well with most Blu-Ray discs. I have a simple, but effective, 5.1 setup that works quite well for DVDs, video games, and anything broadcast or streamed in 5.1 as it has AC-3, DTS, and linear PCM support. But it doesn't support Dolby TrueHD or DTS-HD, and it seemed like the only support I got for Dolby Digital was 2.0, as if the audio wasn't passing through correctly. I don't want to spend more money on a new surround system, especially when the TV I currently have doesn't really make Blu-Ray worth it.
