sounds great when reading the article or Apple's PR material; the only problem is that in reality, it doesn't feel like a click at all. it does provide an interesting vibration type feel, which is better than no feedback at all, but in no way comparable or as satisfying as a click.
Just tried it on the new 13" MBP. It feels exactly like a click, and in no way vibrates. The only way I could confirm it was indeed a new model was to look in preferences at the trackpad settings.
Incidentally, you can still use tap to click as well as having force click active.
