Greetings All- 10 months ago I purchased an Epson 4000 printer, used it a bit, then went off travelling for 6 months. Now that I've returned, I'm suprised to find my "new" 1800$ printer already superceded by the 4800. Why? What caused such a fast obsolencence? Are inks etc compatible? Does Epson have some sort of trade-up policy? While I'm willing to accept the short life-cycles of most digital photo products these days, I feel alittle like I've been ripped off by Epson. I'm sure this has been discussed ad nauseum previously, so excuse my ignorance; I was in China without much contact with the rest of the world. What gives?
