I decided to get the (newer) 2020 Zoom and I am also very satisfied with it. The 2020 Z can be had for about the same $$$ as the 2000. The lack of sound when recording quicktime movies isn't really a concern. I think I'll wind up buying a Sony digital 8mm camcorder soon anyways...
I also bought a microtek CameraMate smartmedia card reader (USB) to hook up to my PC. Had to upgrade the PC from win95 to 98 though, in order to activate the usb ports.
I bought an additional 32MB smartmedia card and a Flashpath floppy adapter, as well. The flashpath works just fine, but it's slow. Also, you have to install the special flashpath software before using it, which Olympus does not tell you in advance. So you need to keep the software with you if you want to be ready to move files to "any" pc. Other than that, it's OK. I mostly got it for ease of connectivity between my home and work pc's, laptop, etc.
For the price of the C2020Z, the flashpath adapter should be included, as well as the case. expect to shell out another c-note if these are important to you. It would also be nice if Olympus had designed a special one-piece battery for the 2020Z, as many manufacturers do. Transferring the four AA-size batteries in and out each time for recharge is a pain in the neck.
Overall, these are minor gripes. The camera is outstanding in every other way, and I highly recommend it.
