Concepts works great, doing the simple things I need to do most of the time but, behind the ease of use, is a very robust and fully featured drawing app that should serve anyones needs very well. Costumer support is outstanding - quick and responsive. I asked a question around 11:30 PM EST about using a feature, anticipating a response in maybe 24-48 hours, and within minutes got a response with clear instructions. I highly recommend Concepts.
