This Canon PowerShot G1, released in 2000 and listed at Best Buy for $800 in 2001, has held up well. Sure, 3.34 megapixels isn't much, but spec for spec, this codger can almost hang with the kids.
Seriously, you could just post this spec sheet next to a Canon in a retail store now, and most people wouldn't bat an eye. They sure as hell wouldn't buy it, but they probably wouldn't say anything, either:
In ten years, what have we gained? More megapixels, higher-quality video, some more ports, better low-light performance, smaller memory cards, better battery life, and a little compactness. Canon's cheapest P&S, the 10-megapixel Powershot A480, handily outspecs the $800 G1 for just $110 (though it doesn't have video). Today, if you hand Canon $800, they'll hand you back a DSLR that shoots HD video:
What's amazing, though, is that if you did spend $800 on this camera back in 2000, you could still use it today. It'd be beaten to hell, the zoom motor would sound like it had gained sentience and learned to experience real, mammalian pain, and the 16MB CF card would have been replaced with something a little roomier, but damnit, it would work—and your Facebook friends wouldn't know the difference. You can't say that about many gadgets from 10 years ago, so here's to you, Powershot: You were great, or your category moves slow. Whichever makes you feel better.
