I just bought a Canon MP390 multi-function printer/scanner/copier/fax and stupidly assumed (without checking) that it would work on OS X. Apparently none of Canon's multi-function units support OS X (although oddly Google reveals that Apple had a Hot Deal on them through B&H Photo at one point). All the other Canon products I've used do support OS X and it appears all their standalone printers and scanners do. I'm not sure what it is about their multi-function units.
Not sure yet whether to return it or to just use it on my Windows box hoping that Canon will soon release an OS X driver.
It's the first time since I bought my PowerBook four months ago that something I've wanted to use hasn't worked with OS X.
I'm seriously bummed.
