What do people need 5V for these days?

External stepper motor drivers. eg:

Driving a stepper directly from FPGA? Why?

Seemed to be more a question of "why 5v at all?", rather than meaning FPGA-specific. ;)

I have a lot of old 8 bit computers, and there's many interesting things you can do with a native 5v FPGA or CPLD there.

I assume interfacing simply with cheap ATMEL and PIC MCUs is another use case.

The university boards can also support 3.3v.

A lot of cheap Atmel micros can run at 3.3v and I think at least some go down to 2.7v.
