I've had mine for a few weeks now, have updated the firmware (very cool), and I've been loving it. I still haven't seen any real HD content on it yet, but I have been surprised how good SDTV looks...even when stretched to fit the screen. Hockey is so meant for the WS too.
The closest I have been to watching HD content is the upscaled DVD's from my Oppo DVD player. I can't tell much of a difference quality-wise between 720P and 1080i, so I use 1080i for DVD's since it seems to fill the screen more than 720P on 1:1. I also picked up a HDMI --> DVI cable from Monoprice, and hooked up my gaming system to it and it was GORGEOUS. My system is on the other side of the room though, so it's not really feasible to use it as a monitor now.
I just need to decide on if I want to stick with DTV for HD and work over their retentions department for the best deal, or wait until Comcast fully takes over Adelphia in my town and go with them. From my understanding cable generally has the best HD stream since it's uncompressed, and they have a solid line with plenty of BW to your house, while the satellite providers compress it. However, from what I've seen Comcasts HD boxes are buggy, and prone to freezing, and if it's the same as Adelphia was, their normal SD channels are crappy wuality compared to DTV.
Oh well, I'll figure it out sometime...
Edit:
I have the 37" 537H, not the 32" non-tuner model.
