OK, well, after a couple of days of using it, I experienced the following:
two-fingered scrolling works, but is still sometimes slow to kick in.
Clicking by touching the pad sometimes doesn't work when you want it to, and sometimes does when you don't.
The machine crashes when waking. I open up the lid. All is smooth sailing. The, I click on an application, or the airport signal, it starts the SBOH and from then on a series of progressively unresponsive applications, forcing me to vulcan-nerve-pinch the machine out of its misery.
so, unfortunately, I'm afraid I will be going back to the old one. Thanks for all the hard work, though!
