Let me know if he needs any other friends!Sort of Apple Watch 4 related... a friend got a new Series 4 for Christmas. So he gave me his Series 3, giving me a major surprise upgrade from my wife's Series 0 watch. It's the cellular model (bright red dial), but I don't expect to turn that on (not for $10/mo).
Initial experience is as everyone said last year: the S3 is much faster than the S0, and generally behaves like you'd expect and hope the Apple Watch would.
