Speaking of Pixelmator, I just noticed it's selling for US$14.99 in the Mac App Store. I'm not sure if this is a discount or the new price. Either way, if you don't already own it go buy it now. For that price you can't go wrong.
I bought Pixelmator for around $30 if I remember correctly, and that was discounted from it's normal price of $50. In my opinion, it's worth the $50 and I'd buy it for that without hesitation. Even with my complaining about it.
