> One thing I think which is overlooked is the raw feeling of speed a good TUI can give you. The lowest grade consumer laptop could probably download my little dictionary program and still get true search-on-keystroke performance, because there is virtually nothing slowing down that path, no animations, no nothing. Now most of that comes down to the data structures involved and making sure nothing ever has to go over a network, but I still appreciate the sheer simplicity of the approach.

Recently, I posted a GUI mp3 playing program written purely in Tcl/Tk using shell scripts for some things. On my 2011 desktop, filtering for a specific mp3 across all the mp3s stored on my computer (about 80GB of mp3s) takes single-digit milliseconds. I can only imagine what a modern desktop, with an SSD, will do!

GUI apps don't have to be laggy. My Qt and Lazarus apps aren't laggy at all, and are far more snappy and responsive than the clear majority of TUIs I use (like CC).
