These are exactly the same problems I have. I have a tendency
to expect to be able to brush my finger across the touchpad
rather quickly and get movement, not mouse click. I run into
a similar issue with a lot of touch (capacitive I assume) control
panels for things like microwaves. For some reason, the designers
seem determined to expect me to hold my finger on them for longer
than I naturally want to. Given that the response processing
of the human brain works on a cycle of around 10Hz, they should
never insist that my contact be more than 0.1S, and I would really
suggest that they register a "press" at 0.01-0.05S. And using
real switches doesn't necessarily fix things. Some people seem
to implement debounce that expects 1/4 to a 1/2 second of contact.
It makes for very painful UI. Imagine a keyboard that expected
you to go that slow...

Funny, I hate trackpads because I'm always
moving the cursor -- because,
call me crazy, I like to rest my hands sometimes and inevitably put my
palm on the trackpad and cause the cursor to go nuts.
Me too. Plus in usage no matter how much I play with the settings I can't ever
seem to get them to a point where they don't register a movement as a mouse
click every once in a while.
