I don't mind the serial check. But they can do that at the CL site.

As for D|S - it's free program. If you're giving away free stuff, asking for a registration is perfectly acceptable. As I said, I have no problems with CP asking people to register to get their freebies.

I'm pretty happy with the way DAZ handles updates, actually. You get an e-mail, with a direct link to the download page of your account. You may have to log in, but then it's one click, and you're done. No searching all over the site for the update, while being bombarded by ads. None of the shopping cart silliness. No suggestions for buying P6 to go with my P6 update. (Though that did have some humor value, I must admit.)
