Have you used PicMonkey?

Someone please remind me why I paid all that money for PhotoShop!  I just discovered PicMonkey and with it, the realization I don't need professional tools to get the results I want!  I have been putting off redesigning my blog head in part because I did not have PhotoShop for my Mac.  I stumbled across a blurb about PicMonkey and within 30 minutes I had a new blog header and a major crush!  Don't get me wrong, PhotoShop is amazing and all.. just not what I need at this juncture in my life.
