I've been trying to find a good photo editor, for amateur use, and I read the two reviews of PE6 in PCA. One says it's great, the other says it's not so great. I've used Serif Photoplus 11, but I didn't really get on with it (never mind the constant unwelcome phone calls from Serif to sell me more).
Reviews, I suppose, are based on short-term tests by the reviewer, and can't match the experience of "real" users. I suspect I shall continue reading reviews while never actually buying anything, which at least gives me 100% discount.
