Umm. My new aluminum MB seems to turn the sleep light on when the display is off...Here is how I see it:
Pros:
- LED sleep light only when MBP is asleep and not like now when the display is off
Oh, there's definitely tactile feedback; it's not like the "tap to click" you sometimes see. The actual trackpad depresses when you click.
- No tactile feedback on the trackpad button
