Since I have code to run tmux or screen in my startup scripts, this is not a feature I ever missed.
xterm does not do the fancy URL-autodetection with click-to-open support
I am very glad for this security feature.
xterm's color scheme can be configured through X resources, but I am not aware of a way to change the color scheme without restarting.
xterm has the best coler scheme of all terminals (especially for 256 colors with/without bold). Why should you ever want to change it and why on the fly?
Lack of fancy unicode support might be an argument if you need it, though I am not aware what should be missing here: I can enter and display all sort of accents and letters (including cyrillic and chinese) without any problems. For my purposes this is more than enough.
One of the very nice features of xterm is the configurable font-size menu and the configurable-size scrollback buffer with an optical indication where you are in the buffer (though the scrollback-buffer alone is also in tmux and screen).
