I'd keep them both - as I mentioned above, you probably want to always print in Best Quality Photo on the Epson - which will be best for photos and your CDs but a waste of ink for everyday printing.

And I'd suggest that your wife print a couple of photos on both printers and compare them - my guess is that they'll both look good separately but that she'll like the look of one or the other more when she sees them side by side - or maybe one will be better for people and the other for landscapes.

Have fun!
