I think that we should use the [tag:macbook-air] tag and the [tag:macbook-pro] tag instead of the [tag:macbook] tag if the question is Macbook-Air or Macbook-pro specific, since Macbooks are discontinued. I spent some time retagging questions that are from [tag:macbook] to [tag:macbook-pro]/[tag:macbook-air]. But I decided to ask "Is it right to do this?" before going any further.
