In the /usr/src/linux/Documentation/devices.txt file you can read more
about these terminals. I would urge to use the devpts system. It's a
virtual system like the proc file system that creates terminals (not the
virtual ones on the console behind your F-keys but the ones created by
programs like xterm) on-the-fly. I think these are the so-called
pseudo-terminals but I'm not sure about the exact names. The devices.txt
and other files that that file refers to will give more information.
Based on that you can decide which static files in /dev/ you no longer
need and want to remove.
A lot are to support your terminals needed by xterm and over serial
lines. A lot aren't needed by regular folks.
