Yeah, and if we take Perl's marketing department circa 2000 at face value, we'd all be using perl6 now. ;-).

I've seen large commercial (expensive, niche-market (banks)) application been rewritten or replaced with Java applets. Succesfully. With large improvements for the customer and/or vendor.

Granted, I don't see many Java applets on the public web. Nor do I really want to.
