Some here:
http://www.dpreview.com/forums/post/55647222Newer UltraChrome HD inks. Driver allows for 10 foot panoramas. Better feed system. Roller for canvas. Wi-Fi. About same price as 3880 of $1,295 w/o rebate.
Same idiotic and wasteful MK and PK ink switch though. Don't know if the ink carts are changed a bit to not allow for refillables - yet. Might be able to suck the new HD ink out of them and put it into a 3880 with a re-profiling.
Does sound like any service needed under warranty makes it a toss-out and get another printer when/if it breaks (So what's new there?).
