Indeed. I was particularly struck today with how miserable my Coolpix 990 is compared to your D1, despite the 990's higher pixel resolution. I swear the chromatic aberration in my camera is getting worse, but even if it didn't exist the accuracy and noise just can't hold a candle to the D1. It remains to be seen where the D100 will fall between the Coolpix and D1 series.
No matter how good the Foveon chip winds up being (it's also suspect until real world cameras and photos exist), the prospect of buying into even a small Sigma mount system is very unattractive. If the reports of a two-year exclusive for Sigma with the chip are true, this doesn't bode well for Foveon sales and market success.
As the price drops come in for the Fuji S1 and the Original D1 I may have the business buy one so I can cheerfully part company with the Coolpix 990. I'll still shoot mostly film, but after a taste of real digital quality I'm ready to move up.
BTW: I just read at dpreview.com that Canon's D60 Canada price will likely translate to $2200 US. That will put some real pressure on the D100 and the Fuji S2 to get pricing in that ballpark. I'll wait a while until these prices are established since that will dramatically affect the used market prices...
