My original plan was to wait until after work to let everybody else be the first ones to update, just to ensure there were no major problems. But alas, I had extra time this morning after getting out of the shower, and I just couldn't hold myself back

.
Since installation time was talked about previously, I loosely timed the install with the analog clock on the wall. From the moment I selected "Yes, Update Now" after signing in to when the screen popped up and said installation was complete, it was right at 2 minutes and 45 seconds. Pretty snappy for a complete overhaul.
I quickly made an avatar, and was pleased with the options. I've read other people's thoughts that the Wii's Miis had more options, but when I had my Wii, I don't remember it having any more options than the Avatars do. I was able to create my likeness pretty easily, and it's pretty close to what I look like:

I didn't go into anything in detail because I was running out of time, but the interface is quick and satisfying, and everything looks fantastic. Can't wait to get home tonight and check it out more in depth.
