I'm also a bit disappointed by the Olympus 25 mm pancake lens, which
isn't really pancake-ish enough. Thinner lenses have existed. Is it
more difficult to produce a small, thin lens for a small-sensor
camera? I figured it would have been easier, as every glass element
was smaller (in all three dimensions) than it's film SLR equivalent.

Pentax has their line of pancakes, but they're screw-driven. If I'm not mistaken, Olympus is the first company to build a pancake with an internal motor. And it's pretty small, given how much stuff is crammed in there.

That said, at f/2.8 it's a full stop slower than the 40mm f/2 pancake they made for the OM system. Not very tempting, really. I don't think it was meant to be an enthusiast lens, though. I think Olympus has backed themselves into a corner with their smaller, noisier sensors and they wanted to pair up the 420 and the pancake as a graphic example of how small and affordable the 4/3 system could be. If they'd made an f/2 pancake it would have cost as much (or more) than an E-420 and wouldn't be something people would pick up as an impulse buy at Costco.
