I just wish all devices were more like PC's.
My desktop computer is a glorious, glorious device. I have millions of different bits of software for it, many operating systems, open source, proprietary, etcetera. It's all there. It really feels like my machine. If I don't want Windows, I blow it away and install Linux, BSD, Plan 9, code my own bootloader, whatever.
My laptop is a bit less so (can't find the perfect form factor for me, can't upgrade it, etc) but it's very similar. It's mine. I have spice, vnc, rdp, ssh, sftp, ftp, irc, <insert a million other things here regardless of whether I actually ever use them> as commandline tools that just work and aren't filled with adverts or in app purchases or 'please add this to your google account'.
Phones and tablets? Complete write off. My smartphone is basically a toaster. Android and iOS make what could be a general purpose computer into a Fisher Price experience. It's really sad to me.
I'd love a modern version of the Psion Series 5. The Pyra (https://pyra-handheld.com/boards/pages/pyra/) looks like a decent candidate. All I need is a Linux distribution with an API or commandline 'sms' and 'call' tool.
The mainstream is basically focused on creating a slightly more interactive version of a portable television, which I find deeply saddening.
