Merlin's Magic Act Not Good Enough. I'll just give it to you straight. I wouldn't bet my money on it. I agree with the reviewers that Release 4.0 is good as far as it goes. The new interface is impressive.
Stability is good.
Java's a plus. If not, there's no compelling reason to convert. And many compelling reasons not to. Like OpenDoc's probable demise. Like flushing away your current Windows investment.
