"Considering Corel? It's good but consider StarOffice first for casual use.. StarOffice's most underexposed feature is its excellent, easy to use drawing program. You'll be amazed by the 3D."
"It's not all that Visio is but it has connector lines, plus the ability to make any connector end you want. Also a gallery for storing prefab shapes."
