I'm curious as to the AVR selection process of others. I know the obvious answer is "It Depends on the application." But, which one part is your starting point? Which part is your staple?
Do you wonder why Atmel even makes a 4K part when you can have 16K? Or, is cost your biggest concern?
Which part are you most comfortable using and you know like "the back of your hand?"
Are you using a part because it came with the development kit, or did you scour over the data sheets for the feature set you thought ideal or universal?
What package do you prefer? Is power your main focus?
Which AVRs are useless in your mind?
