I have that one, only use it on Win XP64, no issues of nozzle clogging, made a die hard Epson man like myself change due to Canon's excellent results, can't say how it works on Mac OS as I dont use Mac.
Yeah, I'm tired of my Epson printer, too. The constant nozzle clogging issue is annoying and costly. The Canon printer should be fine for printing proofs and small photos. The reviews are pretty good.
