I'm confused by the new tab control... is the currently selected tab raised and the tab options dimmed and set into the background? That seems exactly opposite of the way that they should behave. If I was first presented with that control I would assume that the one raised tab was the only one clickable. Or am I just misreading these screen shots?

So mission control unifies spaces, expose, and dashboard but it doesn't REPLACE spaces or Expose right? Have confirmed that spaces and Expose is still present?

While it does reuse some of the iPad UI It doesn't look like a full on iOS coup of the desktop. It doesn't look bad but until I use it in person I will reserve final judgement.

Not a fan of the iOS style autocorrect, hopefully there is a way to revert it to the style of SL as it is annoying enough clicking the x to close when on my iPhone much less on a computer.

LOVE the auto correct features for Lion!

Address Book actually looks like a book in Lion. Cool! Odd to have the window controls on the left-hand page though.

And speaking of window controls, isn't it interesting that they are all horizontal instead of vertical like in the most recent iTunes version? I wonder if this means iTunes will be going back to the horizontal layout or if it will be the only app from Apple with a vertical configuration. I hope Apple makes the controls horizontal throughout the OS.

apple and i appear to have diverging ideas as to where to use colour - when i get a new mac install i always switch the three coloured top left widgets to graphite

was frightened the sidebar will lose its colours after the last itunes update featured the change and am surprised that no other ui elements made their way from itunes - i thought the matte scrollbars would've made an appearance

which leaves me wondering if there are any scrollbars left in the os or is it just a coincidence these screenshots had none (i read elsewhere that scrollbars would appear as needed but i thought that was in full screen mode only)

In general, I LOVE the new UI updates. Definitely looks slicker and more modern. I can only assume they will improve further towards release.
