The problem I always had with inkjets (Canon, in my case) was that once an ink cartridge was opened the ink would gradually evaporate. For my very uneven printing habits this was a real killer: I'd crack a fresh set of cartridges to print ten or twenty pages, come back a month or two later wanting to print ten more, and the ink would be all gone. I used up more ink by evaporation than I ever did printing real pages, by at least one order of magnitude and quite possibly two. Switching to a colour laser brought my consumables cost way down just due to toner being non-volatile; virtually all the toner I buy now actually ends up on pages I printed.

Biggest downside for me is that "one of the smaller colour lasers" is still a bloody enormous box by the standards of anyone used to an inkjet, or even used to a cheap-end B&W laser.
