Smart Response XEs are one of those handheld electronic student answer things used by schools. It's been discontinued for a while, and there a bunch out there on eBay for pretty cheap (~$5-$8)
What makes these nice is that they have a big graphical LCD and a qwerty keyboard. The microcontroller is an atmega128rf, which includes 2.4ghz radio hardware (zigbee or similar), as well as 128K flash, and 16K ram.
I bought a few the last time they were featured on Hackaday. These were poised to be the next IM-Me style hacked device, but I haven't seen that much development on them (just a couple in 2018-2019). Perhaps that's because there isn't a whole lot of information about them.
