@archerbob said in Questions on the use of Ubuntu Touch:

Can I use Windows apps on Ubuntu Touch?
Can I install & run PC Games?
Can I use WINE?

In terms of all of these, it's really not about Ubuntu Touch, but about what you're running it on. In any case, Ubuntu Touch is not Windows, so you can't directly run Windows apps on any architecture. With the very experimental amd64 qemu image build, you can run Ubuntu Touch on a PC (however lacking the experience may be currently, due to a lack of touch interface there), and can theoretically install Steam, WINE, and other things inside libertine and run them, though the performance or usability may not be ideal.

Otherwise, not really, no. Phones/tablets are generally made with ARM architecture CPUs, which are not compatible with x86 binaries. Remember, just because you can plug in an external monitor, and have an interface similar to your typical PC, a phone is still not a PC.

Can I use Ubuntu Touch to remote to another PC (Windows/Linux) and control that PC via Ubuntu Touch?

Theoretically yes. There is no native VNC/RDP app in the Open Store yet, that I know of, but if there were, you could use it to do so. Beyond that, you can however use ssh to connect to a remote Linux system and do things on the terminal (X forwarding will not work yet, as Ubuntu Touch does not use X, and Xwayland is not yet working on UT).
