Pete,
I'm with you: I think the Canon announcement was intended to counter the HP product debut but it's still a long way from getting into the marketplace. And even when they do roll out (assuming they actually do), Epson has had their products out there for several years and a few iterations. These iterations of the 1800 and 2400 -- and the new K3 ink set in the 2400-- are pretty refined.
Like you, I'm going for the Epson product. Now, which one? Decisions decisions.
Jim
