I have used the plain old System.Random exclusively for years now and did 
not encounter any problems, but I also did not watch for them. I used 
System.Random for Markov chains, audio noise generation, randomized 
algorithmic music, board game computer opponents etc. I'd like to keep a 
default random generator for the many cases where I don't care about the 
precise algorithm. That said, I got used to some randomized synthesized 
sounds and randomized melodies such that I already noticed changes in the 
random generator implementation.
