What are the best alternatives to Adobe Creative Cloud?

Kevin is looking for an alternative to Adobe's Creative Cloud since he thinks that $40 a month to use Photoshop is too much. Leo says that Adobe has been wanting to do this for a long time. Adobe is afraid of piracy and have figured out they can make more money by renting out the software instead of selling it.

Here are some other solutions:

• The Gimp
• InkScape
• Pixlr
• Paint.net
