How I use the glass trackpad:
- Never physically click it. If you do, it'll only slow you down. Turn on Tap to click and use it, double-tap+hold for dragging, double-tap for double click.
- While dragging, you can even let got of the trackpad for a second to reposition your finger and it won't release the object you're dragging. It's really smart about it.
- Get used to using four fingers down/up for Exposé and Show Desktop. It's a lifesaver shortcut 😀
Needless to say I absolutely love my glass trackpad. I once even used my friend's original MacBook and it was soooo crap compared to my UMB's trackpad!
