We have both in our company. And they stills struggle with Python 2 in many cases because software just never got updated to 3 (but still is somewhat active). While our Ruby team could just upgrade one after the other thing, especially as most gems pretty soon supported 1.9 as well.<p>It is also worth mentioning that i still need to have Python 2 and 3 installed to properly work on my Linux box. But i havent had needed a Ruby 1.8 since at least 1.5 years now.
