The only thing I need and haven't found in others is Slack's functionality of drawing on someone else's screen. Webex has it but it's super cumbersome to use.
Until that keyboard breaks. Quite a few reported issues for both the KEYone and 2 where the space bar and fingerprint reader just stops working, thanks to TCL build quality. And they are terrible with upgrades, KEYone only got Oreo, and certain versions didn't even get that upgrade at all, in particular the CDMA version, both locked and unlocked.
I don't know what build quality you were talking about, they weren't exactly known for that. I guess you forgot about dying trackballs, double-typing keyboards and lifting screens.
Definitely something with your machines. My 3 year old ThinkPad X120e with the miniscule AMD E350 processor runs fine with Windows 7. Even my old single core XBMC machine with 2GB memory ran fine until I switched it to Linux (not for performance reasons, though)
