Indeed - truly good programmers can/do use more then one programming language. And with Java being still the No 1 Programming language
(TIOBE, The Transparent Language Popularity Index) Apple is going to loose quite a lot of developers and customers.
And yes I read all the fuss about Desktop-Java is dead. Well maybe. But not for Software developers. Those need/demand working IDEs and in most cases this means Eclipse or NetBeans. Both of which also support a host of other languages. More then XCode does. And using a simple text editor is not an alternative. An IDE - especially for server side development - does a lot more.
Without a viable alternative I will have to move back to Linux in about 2 years time
🙁.
