Surefire way to make me abandon all good sense and pine after something: take an existing item, product, or whatever, and shrink it down.

For example the NES/SNES classics, small bottles of sauces/beverages, netbooks, etc.

I'll very rarely actually break down and buy of these things (unless I have a practical need), but it will force me to pause what I'm doing, go "OMG CUTE" and consider it for a few moments.

I'm probably incredibly shallow.
