I used to use Photoshop at work, but at home hands down its the Coreldraw suite. You get 11 products cheaper than the price of one. Grant you Photoshop is better than Corel paint, but usng Corel Paint and Coreldraw together, seems like there isn't much that you can't do. Do you Coreldraw addicts agree?
I started out MANY moons ago using Corel Draw and I agree that it is an AMAZING program and super easy to use. However, since a good chunk of the design world uses Adobe products, I switched over to Illustrator and Photoshop a few years ago and use those exclusively now. (Sorry Corel Draw... miss you!)
I even used coreldraw to do the workup for a unheard of feature film. Miss Castaway, the aircraft graphic skins were done in coreldraw then applied to my model in 3ds Max.
