I'm not fully sure as to why everyone says it sucks. It's going for $799 now, plays both formats, and works fine. The only couple things I don't like are:
1). HD-DVD interactivity is missing. Not a big deal for me; I know HD-DVD's biggest thing is the new interactive features, but I just don't use them on my A2. I like to watch the movie.
2). Dolby TrueHD surround: It doesn't work through HDMI, and I don't believe you can get more then Stereo through analog 5.1. While TrueHD is nice to have, it's not 100% necessary for most (though I would not buy the player for this reason alone).
That said, everything else about it I like. It loads Blu-Ray/HD-DVD MUCH faster then any other single player out there. I have the Pioneer Elite 94 BD player next to the LG, and it's almost night and day when it comes to load times. As much as a minute doesn't sound too bad for a player (like the Pioneer), in practice, waiting a minute to put a disk in is unbearable.
It's also more stable then any other Blu-Ray/HD-DVD player I've ever had/seen. We've had tons of problems with the Samsung BDP-1200/1400, Pioneer Elite players, and even the Sony's. None with the LG...so far. No hard freezes, needing to reset, losing the HDMi signal, etc.
That said, $799 is still pretty steep, considering you can get an HD-DVD (A2) and Blu-Ray player (S300) for the same price. Even so, the convenience of one unit for MOST customers may be more important. Just something to think about.
