I try not to post too much about things that are wrong, except that sometimes things just confuse me so much that I have to.
So imagine when you go to windowsupdate.com and find that IE7 is available, and you say, oh gee, I guess I will install it. And you reboot twice...and your disk grinds through 30 minutes of updating and installing.
And at the end of all this upgrading, you have IE6!
But wait, before you had the IE7 beta. So of course you have no idea exactly why this happened, but you hope this isn't Microsoft's idea of a quick update.
To contrast: Firefox 2 on my MacBook, took 5 seconds to update from 1.5. Really, open the .dmg, drag a thing, wait 2 seconds, done.
This kind of complexity just doesn't make good sense.
