I've been running ruby 2.0 (p0 first, and now the new patch release) on linux (intel laptop and raspberry pi) and Mac OS X, without any problems. Barring a few incompatibilities with 1.9 (UTF-8 as default encoding probably the biggest one), it shouldn't be a problem. (See http://www.ruby-lang.org/en/news/2013/02/24/ruby-2-0-0-p0-is-released/ about this.) -- Posted via http://www.ruby-forum.com/.
