I tend to agree … it’s really not fair, only more sniping, to assume that someone is blaming problems that someone else imagines they have on the tool. That said…
This is just full of pure unproven assumption: Please tell us how you know that when the Windows version comes out, the Mac version will have new or better features than it does. What access do you have to L&L’s budget and personnel deployment? Have you tried the beta? Many users report that it is quite usable and safe (basically all the responses to the similarly constructed whinge here). It also remains to be seen whether or not they hit the end-of-August target.
Overall, I just find this childish. And I say that as a person who frequently has pretty childish outbursts himself; it does take one to know one.
