"The second mouse gets the cheese." - Since my iBook died multiple deaths via its BPGA socket, I've learned to buy rev. 2 or rev. 3 products for all my Apple purchases, when possible. It's consistent with my experience in avoiding x.0 software releases. It's really cool when a company treads new ground, but if you need reliability, it's best to let others test the first round.
Yep. Toyota seems to release their Corollas in three year design cycles. I wonder what the distribution of 300 kilomile Corollas is across those years. My guess is that the 300 kilomile population is highest for the rev. 3 cars.
