The big thing for most people I've talked to about Ruby 1.9 is not so much when the next 1.9.x release will be, but when will most of the frequently used gems be compatible with 1.9?
It took awhile before Hpricot, a widely used gem, was updated for 1.9, but it seems even that now works. Of course, with Nokogiri, people now have another choice.
Good to hear that most gems are working now.
I still haven't tried any of my Rails apps with Ruby 1.9, just standalone programs.
