I really can't agree with any points you made, Brad :/
1) Standardized benchmarks. Hooray, it's going to be easier for the average person to understand what will and won't run.
Lets be fair, the majority of us posting here probably already KNOW how the specs on a game match to our PCs, and how well it'll run. This is for the casual gamer who isn't really interested in computers. I can't see how it'll affect me at all.
2) I have shortcuts for game directories on my desktop, so I can run the client or start modifying it by double clicking anyway. When I was modding GC2, I think I had 5 shortcuts to various folders, so I could modify them all without manually navigating. What's the new explorer got to offer that old shortcuts couldn't do?
3) This is great for people who didn't pay any attention to what their kids played and don't want to go to the hassle of caring. Sorry, but it'll more than likely just turn out like internet parental controls, IE disabled within about 3 days. Built-in parental controls are generally weak, and the only way to actually utilise them is to know how your computer works better than your child does. And if you know that much, you should know enough to not let them buy completely unsuitable games.
4) Joy, I can now fork out for a $600 video card to play any new games built to work on vista. Oh, and I can upgrade to vista. Huzzah. As said, it's just
A) make DX10 vista only

make DX10 OMGUBERHAWT USE IT OR FAIL AT GAMES
C) Profit!
5) So solitaire and minesweeper will look shinier? I've never been a fan of built-in "casual" games. I suppose it could be good, but I doubt it's worth vista.
Yes, I'll be getting vista. EVE is upgrading to a dx10 client and the images and models show the graphics blowing every other game in existance out of the water. I like pretty explosions, so I'll be getting it, and a stupidly expensive video card too. I'll probably have to upgrade my entire computer to get it to run nicely too.
I'll be getting vista, but I'm not doing it because I like vista. I'm doing it because DX10 is vista only, and I'm certainly leaving it for 6 months so it can "iron out the kinks"
Bleh.
