Hi
I don't have 10.1 yet so I will post my full report next week. Now........
I could probably agree on the clock thing.
A hard drive does get it's butt kicked if you do that. I didn't know that right away with my PowerBook but I got a nice crash once and the ? disk icon and now my hard drive is noticeably louder. Plus it does take more energay to spin it up and down. It would do you more good to just turn the brightness down. I have a PowerBook G3 Lombard.
Dock Extras I could care less.
The Energy Control stuff maybe kind of half way care. OS X is pretty good with power usage now.
The Inspector (Get Info) is no biggy. It kind of stinks but easy work around is use your brains memory
The background thing is just eh not that big of a deal if any.
As of right now none of the other issues really matter.
And the Mail reply address. You ever hear of preferences? Try 'em sometime you'll be amazed.
Plus these features way out those big time........
DVD playback and recording
CD recording
SPEED!
Updated system components.
Airport
New Aqua features.
I am probably forgetting things but you get the point.
I can't wait!!!!!!!!!!!!!!!!!!!!!!
