While I was out running errands, I stopped in at Best Buy, and lo and behold... they had it! I got the last copy at the store, but was surprised they had it all the same.
Back on the D2D vs Steam, I've used both for a number of games. If I had to chose between the two, I'd use D2D. I've never had any problems with "redownloading" games I've purchased. I had been using the "Release Candidate" version of Windows 7 (which expired on the first) so I had to do a "clean install" of a licensed version of Win7. When I was reloading some of my games from D2D, I was DLing at 1.2-1.5 mb/sec! That's the fastest I've ever seen a DL on my connection. Since it was DLing so fast, I started several others, and had 5 games DLing all at the same time. The slowest out of all of them with 5 DLing was running at about 500kb/sec.
If you want the disc, you might try some of your local "big Box" stores, they may have it. See ya on the Seas!!
