Calling all you creative minds

An icebreaker activity we are doing for a class I am teaching (of adults) is to lay out a bunch of items and have people take one. Each of the items, or "technologies," will be part of a matching pair. One will be an older version of the technology, one will be a newer version. The item itself doesn't necessarily have to have been crafted prior to the other one, but it must be clear that one is a newer technology of the same thing.

Examples of items:
Analog watch/digital watch
Hand eggbeater/electric blender beater
Cotton sock/Synthetic sock
Hand fan/electric fan
Old phone/new cell phone

These must be items you or I already have lying around the house, as we have zero budget for any more items. They also must all fit in a bag I am carrying in, so please don't say "old TV, flat screen TV." I'm having trouble coming up with unique and creative items. I need 15 pairs of them! Put suggestions here please. Be as creative as you can think of! If you have any of the items you suggest that I could borrow, I'll happily return them to you. I only need them for one day (July 6). Thanks!
