Just got my Panasic BD30 (an hour ago). Nice machine and viva HDMI (one single cable + power chord! and 2-3 settings and I have DolbyTrueHD and so on piped directly to receiver)!
I also have an A30 for HD-DVD. The main reason I switched now (although depending on price I might get more HDDVD titles too) is that I already have 3 friends who just went Blueray. it is a lot more economical when we all have the same format so we can exchange movies and series and keep the ones we want to see more often.
