Oh, I agree...
I actually have a 12.9" iPad, anybody who thinks it's comparable is smoking something. The one big advantage of the iPad is the built-in cellular connectivity.
But... the 12" MacBook is a niche product that doesn't fit in with the low or high end of the lineup. If they resurrected it, I think they should call it MacBook nano or MacBook mini... or actually, it SHOULD be called MacBook Air except that "Air" means "low-end" in the post-2015 world.
But my worry is, a MacBook mini would be... about as niche a product as the Mac Pro.
(Also, did you buy yours new? I will admit that I didn't... and I would never, ever have spent whatever the price tag of an i7 MacBook with 16GB of RAM was brand new. So as much as I like my 12" MacBook, I paid 1/4 of its new price for it and got it as more of a toy than anything... and meanwhile, I paid full price for a launch day M1 Max 16" MacBook Pro. So... as far Apple is concerned, they had the right product mix to sell to me.)
I did the same and bought MacBook 2015 for 1/4 of the price as a "toy"...have a 16" MacBook Pro 2021 for the battleship tasks and work. Would not even consider buying new for the price when it was out.
BUT... after using it for a few months, it is no longer is a toy and became useable in my workflow to my surprise. Typing on it now...
Perfect size for me just for traveling or sitting on my couch (laying actually) with a pillow and doing some work with it. The keyboard of course after awhile typing - my fingers get tired (butterfly keyboard), but it is ok for what it is. Underpowered of course, but Big Sur with the latest patches seems to be running faster. Safari's offerings seem much faster also.
So overall (to my surprise) my old "toy" became adopted into my workflow as a main part now. If I knew it would be
this good for me, I would have spend a few more pennies to get a 2017 model when I had a chance, but I wanted the gold version and it was in perfect condition (except for a few small specs/scratches that are not noticeable when the screen is on due to top lip of the trackpad - like old Airs issues).
Since I paid $325 for it at the time, I went to Apple and replaced the battery before the price hike, so I am set for some time with this little gem!
Hoping...Apple...comes out with another...even if it JUST has an M1 in it...but..."if" it had a M3................
