In response to Gollums comment on the library. Apparently they have the practically the same amount of movies released (or listed to release). You can do a search on Amazon and currently HD DVD has 124 titles and Blu-ray 117. Of course, who knows what gets distibuted to stores and maybe the HD DVD are more distributed.
As far as the player, I would be hesitant to get the $1000 player if it could possibly be buggy. Samung has a player that has been marked down to $699
BD-P1000 
The PS3 however, seems the best deal. $600 for a game console (the best in the world) AND a Blu-ray player. I hope the bugs are all out of this one!
