Can confirm. The 16” MacBook keyboard is a phenomenally good laptop keyboard. If you care about typing and don’t want a large laptop, I recommend waiting for this keyboard to end up in other models (which I’d have to imagine will be happening any time now).
I just looked at these laptops and like the Mac Mini sale-a-thon from last month, these are not great deals. These are mostly 2011 and 2012 model year laptops that are no longer supported by Apple (so no security updates for you). The “black” MacBook Air is just a silver one with an aftermarket case on it. That’s not confidence inspiring.
Unless you really want an 8-9 year old laptop, you can get much better deals on newer refurbished laptops with a warranty directly from Apple.
I’m all for recycling perfectly good computers but make sure you do some research to know what you’re getting.
