I used to love Java. Although I think they ruined it with the concept of "Enterprise Java" which only complicating how they were delivering the software. Many good things came out of this work that has been ported to many other frameworks (although, not with the enterprise branding)

Java is not slow, I use a couple of high quality desktop applications and these will most likely have a future as long as the language is developed. These are not slow apps. Bad developers make bad software regardless of language.

One of the main things that I always struggled with was the IDE of java. Buggy, slow and overly complicated. I saddens me profoundly that java lost its "je ne sais quoi"
