Here's some random thoughts. I don't have a fully formed opinion on the
topic, but maybe these general observations can help the discussion.
* There are several different loose categories of devices we're talking
+ Integrated Apple pads in laptops
+ Apple magic touch mice, plugged in via USB(?)
+ Integrated pads in netbooks (like Dell Mini V)
* People have widely divergent views on how their pads should behave.
+ Changes to input behavior that can be perceived as a regression by
any group of users tend to spawn bug reports and/or complaints.
+ We can't please everyone.
+ We want to minimize the number of people who have to configure
things, that didn't have to configure things previously.
* Historically, we've not been prolific with X input SRUs.
+ Partly because many input "bugs" are just differences of opinion
about what options should be the default.
+ Partly because input bugs often involve patches that are complex or
+ Partly because testing the changes requires a variety of input
hardware that many of us don't have on hand. (Testing can also be

don't get to input stuff that often.

different expectations than existing users (or windows migrants).

converts to Precise?)

"ClickPad + RightArea"
It's hard to construct a solid opinion on the options... so many
If we definitely want to attract Apple converts to Precise (or make it
easier for people who swap between OSX and Ubuntu), then it follows we'd
at least want to make ClickPad enabled by default for Apple hardware.
Do we have strategic guidance from Design or management on what we
should be prioritizing here?
However, what I've heard from many Apple laptop owners is that there's
so many little quirks and misbehaviors, that ClickPad-vs-Traditional
might be just one in a long list of support issues. If we fix that, but
as a result break something else, we may not really be gaining that much
in total. But I don't know.
Leaving Apple hardware aside, for non-Apple hardware where we don't have
expectations for ClickPad functionality, it seems like it would be safest
to leave that as Traditional + ClickActions. This assumes we can ship
one option for Apple stuff, one for everything else. If we can't, then
that seems to suggest we should stick with Traditional by default, and
wiki up directions for Apple users.
If we decide to move to ClickPad or ClickPad+RightArea as the default,
we better make sure we document how to revert back to Traditional (even
if it means installing some PPA with downgrade drivers or some such).
Otherwise we risk earning some serious bug reports.
Again though, these are just some loose thoughts, not a solid opinion.
