Lots of enterprise apps like ERP and that type of shit may STILL require Silverlight for older versions. It was huge in that market.
I still miss macromedia Director though. I learned to program with HyperCard and then director, and I always thought it was a shame it got canned when adobe bought it.. it was much nicer in lots of ways, although the player was more heavyweight. Actually, I don’t think I’ve ever really found a proper replacement for HyperCard!
