It took a while for digital cameras to catch on, but once prices dropped in the mid-'90s, the market exploded. What used to cost a couple stacks now costs a couple c-notes. It has become one of the most viable consumer tech segments, with brands offering entire multi-tiered lineups and a camera for each and every price point. The only bad thing about everyone having a digital camera? It's increasingly hard to get drunk and not have it wind up on the Internet the next day.
