Excellent detailed review as usual, Keith.
The stumbling block for me will be the cartridge sizes/ink cost. I'd really like to replace my 4900 (sold,moved, loved) with another sheet cassette printer, then adding a 24" sheet/roll printer. 13" wide would be ok for a smaller printer size coupled with (finally!) the ability to print smaller than 8x10 sheets, something I longed for with the 4000/4800/4900.
I believe Epson is expected to roll out a couple more printers in the next few months, yes?
