About that trackpad...

Go to 42:30.
When I upgrade I think I'm going to miss my real button.
Honestly... he's just being stupid.
If you look at his hands... He is trying to use ONLY his index-finger to:
a) press down on the trackpad to initiate a click
b) move said finger WHILE keeping the pressure of the klick, to move the cursor
ofc that doesn't work (well, or rilable... YMMV).
The only RIGHT way to do is... is like it was done in years past... when the MacBooks/iBooks/PowerBooks still had a separate physical button.
Navigate with your index finger. Rest your thumb on the button, and use that to actually click. Or click and hold for dragging stuff etc. (Taps on the trackpad are ofc always an option too.)
Apple KNOWS this. That this is how it SHOULD be used. And that most people actually DO use it like this, which is why the button-less trackpad was always rather smart:
Normal configurations state: One finger on trackpad = click, two fingers = secondary click
If I rest my thumb on the trackpad though... aren't there alrdy two contact points? Why yes ofc. But the thumb at the bottom of the trackpad... is 'technically' only resting on the button... so it doesn't count. You can just leave it there... and STILL perform normal (left) clicks.
The way how the engineer was using the trackpad... well... even if it still DID move physically... is a pain in the ass. Having to keep up the pressure on your index finger while moving it across the trackpad's surface... not such a great idea.
I do not currently own a click-less MBP... but used one numerous times... And while the click does feel a tiny bit weird... I never had ANY issues with it. What was a bit ridiculous with the iPhone 4... here is actually true...
"You're using it wrong!"
