There's so much wrong with the SD series DSLR's (and their SA series film SLR predecessors) that it's hard to nail down anything close to a crucial weakness. No JPEG wasn't a big issue given that pretty much everything else about the Sigma's sucked worse (Bodies that would have been obsolete if 10 years older, AF which barely kept up with a Maxxum 7000, overly small, low-resolution sensors with ridiculous marketting, an inability to get good files over ISO 400, bad metering, very limited lens options, poor handling, high pricing, an inability to ship within 2 years of announcement, etc). The one thing the Sigma's have going for them is very nice per-pixel sharpness (the much vaunted colour accuracy of the Foveon X3's is in fact non-existent, Bayer sensors produce significantly more accurate colour due to having less channel overlap. The only colour-related advantage of Foveon is that colour aliasing is impossible).
