no, not based on history. check it out over at the apple museum
you can clearly see that they don't simply 'pick the next number' for each new machine, it follows a very clear pattern. Of course, a couple of interesting things come out of studying the lists...first, the very first iMac (rev.s A through D) is identified as iMac,1 but all subsequent iMacs are clearly labeled as even numbered "PowerMac,"s. Also, and more telling, is that the 12" PowerBooks are all lumped in with the iBooks as part of the "PowerBook6," category. Also, notice that the convention of odd numbers for "pro" machines (vs. even for "consumer" machines) is even used with the "RackMac" identifier, the one id category in which it wouldn't matter, as there aren't any "consumer" rack macs. This should make it very clear that this even vs. odd breakdown is not coincidence, but rather a well maintained policy.
And the fact that the 12" powerbooks are even doesn't really imply that Apple see's them as consumer laptops, but rather that their "guts" are based on the previously engineered consumer iBook's guts, which we all already knew.
Very interesting stuff...
