People might find this funny, but I do still use a Q700 when I get bored for my back-end programming/scripting on my webserver. I temporarily enable the legacy FTP protocol so I can get in, and edit all my PHP Scripts from there. Otherwise my FTP stays on FTPS and SFTP enforce with modern ciphers.
I dont do any modern HTML code from that machine, but I do all my back-end/database PHP Scripting with it. ;-)
Other than using it as a mundane word processor, thats about the only modern task I can do with it.
