I wonder how much battery power the thumping consumes. It is very convincing, to be sure. For the most part I'd prefer real switches, but haptic feedback when moving the cursor across UI elements can be pretty cool. Can't say I've encountered it in any applications I use, though.

There are two major failures with the MacBooks' trackpads:

1. They're too big. You can't put your hands on home row without frequent spurious UI interactions. Most often this is a click being erroneously interpreted as a right-click, because the pad detects that your non-clicking hand is still in contact with the pad. But frequently when I'm typing, the cursor jumps to some other part of the page or edit box. There's just no reason for such a large horizontal area; you essentially never use the whole width of this giant pad for horizontal scrolling or side-to-side movement.

2. The giant trackpad can't be used with the Pencil. This is just baffling. Its surface area is plenty big enough to be useful as a drawing tablet, but the Pencil doesn't work on it. Why? I'd buy a Pencil today if it did. At least then there'd be a payoff for the dumb size of the pad.
