1. Mine is networked, with the Epson adapter. This does not discard any problems with the driver ("Do not color manage"). I prefer 10/100 greatly over parallel connections since my computer drives 4 printers.
2. With ICC control on ColorLife paper, the gamut is virtually the same as the 4000 on glossy. Glossy gamuts are a bit contracted, but not to the point of profoundly affect existing light shooters.
3. 720dpi is virtually indistinguishable from 1440 on gloss, and takes about 4 minutes to print an 8x10.
4. ColorLife paper is a matte, and is superb. There are a number of third party suppliers of paper and profiles (inkjetart.com, et. al.) that can make life easy for you.
5. My printer prints warm on generic profiles, including those supplied by Epson.
6. I had trouble going with even the higher quality third party inks. Couldn't get decent black rendering. Conventional wisdom says "avoid" all but the Epson inks.
7. Overall image quality is superb.
