Congrats. I had every intention of waiting for the war to sort itself out a bit more before jumping in, but near the end of this past summer, I jumped on a deal at Amazon where I got the HD-A2 plus 3 combo HD-DVD's(chose 300, The Departed and Happy Feet) for $210. Plus the 5 free HD-DVD's through Toshiba of course. This was too good to pass up. Since then I got the price reduced another $20 when Amazon reduced the price on the A2. So all that for $190.
I really love the A2. I use it with a Pioneer 1080p 60" plasma (6010), and it is stunning with HD-DVD's. Upconverted SD-DVD's look excellent as well. I do still keep my Denon 2900 connected for DVD-A and SACD.
I have over 500 SD-DVD's, and basically have no free time to watch them, so they mostly sit idle. So the last thing I really wanted to do was to start buying more DVD's (albeit in HD). But you know how that goes.
So I now have about 15-20 HD-DVD's, and although I really don't plan on going crazy buying HD-DVD's, it is fun upgrading some classics (like Goodfellas, Casino, etc.) or buying some fun new movies (like Hot Fuzz and Shaun of the Dead), or buying good movies that look fantastic (like Batman Begins, King Kong, Troy Director's Cut, Matrix movies). Documentaries like Planet Earth and Galapagos look amazing.
So have fun. At these prices, it is very hard to resist taking the plunge into HD.
