Well I hear a lot of “silly boomer, don’t you know a computer is a computer and a phone is a phone” but many whippersnappers don’t know that Von Newman proved all computers are equivalent in theory and video game emulation proves they are in practice.
I think the barriers that exist depend on path dependence and other accidents of development. The laptop has a hinge and a trackpad that help you when you are flying on a plane. 2-in-1s drove stewardesses crazy because they couldn’t figure out if you had to stow them for takeoff. For that matter battery sizes are limited because of the needs of that industry which might seem justified if you live in NYC and can fly to London for what it less to costs to fly from my small town to NYC. Maybe if they’d invest in my community I’d care what they think but I think it’s unjust.
All the time I use a cheap plastic clip and a cheap Bluetooth mouse and keyboard and RDP into a monster computer from my tablet. If I have a real desk or table it’s fine, if you really have to put your laptop on your lap that hinge looks like genius. I’ll grant the 2-in-1 can be demoed at CES and the Bluetooth-based system can’t because they have too many devices in too small a space for Bluetooth to be reliable.
Even if I don’t have the mouse and keyboard I can still do a lot with the touchscreen.
The worst thing Win 8 revealed was that you could have the ‘windows’ keys on computer keyboards for almost 20 years and nobody noticed because…. It looks like an ad and people think anything that looks like an ad “just doesn’t work” (as opposed to “doesn’t just work”). If you were missing the start button you could just push that button but people treated that like putting their hand in the toilet.
