I'm using a Z505HS with the long-life battery, and this works very
nicely for me.   Battery life is somewhat >3h.   Unfortunately, the
long-life battery adds a bit of weight, but it's still incredibly
light.   The new Titanium from Apple might be a nice solution, because
the processor burns less power, but I don't know if NetBSD will boot
on it.
