Which is really silly, because if someone needs to do actual work they are not going to do it on an iPad no matter how capable it is. The form factor simply does not work for getting work done. Apple has nothing to fear here.
Nonsens. The iPad is basically a 11 to 13 (Pro) monitor+computer with an amazing touch screen. Adding the official keyboard folio, or any bluetooth keyboard/mourse is trivial, and it makes for an excellent on-the-go machine. Not different to the 12-inch MacBook (circa 2015) and the older fan favorite 12-inch PowerBook G4 (circa 2003), and I know several devs who swore by them. Linus used and loved one of the latter (with PPC Linux on in his case).
The only issue is the lack of OS level support for some stuff, not the form factor.
Admins, devs working mostly on the Cloud, photographers, and writers already use it for "getting work done", I've seen execs too.
They’re pretty aware they’d be cannibalizing their lower-end laptop lineup.
