> I got maybe three hours of the supposed 7 hour battery
You should have taken it back. Seriously.
> Perhaps I'm set in my ways
You hit the nail on the head here. There's nothing wrong with that but most of your complaints amount to "this is not what I am used to".
> the absolute insanse window switching behavior
On Windows and Linux I cannot switch to an app bringing all windows to the front, I have to do it one at a time. Anyone used to one behaviour could claim the other is insane just because it is different.
> the piss poor excuse for a terminal
What on earth are you talking about? The Terminal app? Get iTerm2 or something else then. If you don't like gnome-terminal you don't whine about it, you just install urxvt or whatever.
> the fact that apps continue to run in the background after you close the last window
The fact that you have to have visible windows for an app to run on Windows and Linux could be perceived the same way. What if I wanted to switch back and use that app again?
