OK, my wish-I-had-a-device-that... list is:
--a program I could plug my ideal literary argumentation essay into and then attach my student's essays and switch it on and it could grade them overnight.......
--then I need a robot that can clean bathrooms to my standard and specifications. I'd say such robot was called "husband" but I have failed to program him to work to my specs.....
I'm sure I could think of more.....
