Paint Shop Pro is available only in Windows.
Con PSP8 has a relatively slow startup
PSP 7 worked better than PSP 8 in terms of startup speed. There are still versions around somewhere, if you look hard enough.
Con No more updates available
Paint Shop Pro 7 was pretty stable, but its creator JASC Studio is no more. It has since been acquired by Corel, and rather than improve Paint Shop Pro, they have killed it.
Con Windows Vista and upwards have limited support for colors
The main issue with PSP is that Windows is forced to "change" your window's color scheme while the software is still running. This causes screen flickers and odd color effects.
