when we introduced the synaptics touchpad (to replace the extremely
troublesome, and decreasingly available ALPS pad on XO-1), we
discovered that it did tap-to-click by default.  reaction was somewhat
split -- as you say, some users like it, but feedback from deployments
said that children tended to find it extremely confusing:  actions
that they intended to simply cause motion would cause something
altogether different to happen, and it was difficult for them to
understand why.  so we went to some effort to disable tap-to-click on
synaptics.

then the AVC touchpads were introduced, as an optional second-source
for the manufacturer to use.  OLPC of course approves such changes,
but the user-interface impact slipped past us at the time.  the AVC
pads also enable tap-to-click by default, and for uniformity we should
have disabled it by default.  but it require a different command
sequence for disabling, and for various reasons the change didn't
happen until today's os7.

so the answer to your question is yes, the presence of tap-to-click on
your laptops is unintended.

it's not out of the question that this could be made user-selectable, but
there are no current plans to do so.
