For anyone who has one of these, could you tell me if it says gigabit ethernet anywhere on the box? I recently bought the non-gigabit one and switched them out at my local store today (the Apple people there don't seem to be hardcore fans, don't tend to know subtle things like the silent gigabit ethernet upgrade)... anyways, someone claimed that it was "newly unboxed", and it did have a new model number, but I don't see gigabit anywhere on the box.
