While I don't like Photoshop's interface and consider it counter intuitive to most Mac drawing tasks (it is a photo editor, not a graphics package), hats off to Pixelmator for providing a near-zero learn time for anyone familiar the Photoshop.

At 1/10 the price of Photoshop and easily 10 times faster at startup, Pixelmator is suitable for 80% of what Photoshop does. Most people who think they need Photoshop could do nicely and better with Pixelmator. It is definitely worth a try. I don't use Photoshop at work or at home any longer because of Pixelmator ... and liked this so much that I bought a personal copy instead of asking work to get my Photoshop upgrade.

This one is a real gem and I do not hesitate recommending it.
