If the largest vendor of computer hardware on the planet purposely locks down its devices for no apparent consumer benefit then informed users have every right to complain to the less informed how this harms the entire market in the long run.
Agreed. The iPad, from a hardware point of view, is a close approximation to Alan Kay's Dynabook concept (https://en.wikipedia.org/wiki/Dynabook). It's a shame that iPads are so locked down; I'd love to use an iPad with an unrestricted operating system.
I have a Microsoft Surface 7 Pro. Even though Windows is not my favorite operating system, I enjoy using the hardware. I'm also looking forward to Framework's upcoming 12" convertible tablet; I also have a Framework 13 laptop.
