I don't know how long ago that was, but I've been a Pixelmator user for at least a few years, and it's leaps and bounds ahead of where it was when I started with it. Coupled with Photomater -- its cousin app -- they're certainly starting to give Photoshop a real run for its money in many ways. Of course, not all ways, at least not yet, but I have personally used it for everything from photo touchups to marketing collateral to art elements later incorporated in a range of things including print layouts and videos. Once in a while I bump my head on a missing or incomplete feature that I was surprised to find not yet implemented, but its getting rarer by the month.
