Still used to move some network firmware and config files.
With the work done on gpxe tftp is rather useless except in legacy deals.
What do you want to use tftp for?
I need it to upgrade the firmware of my router.
The latest firmware can't be updated through the web interface,
you have to send a 'get' request from the routers' telnet console to a tftp server running on the computer to get the update file.
