I failed a subject (operating systems) because I couldn't manuever the code in Eclipse. I once quit Android development because of Eclipse, and came back because they switched to Android Studio. I got 300 upvotes on a topic that was just debugging wonky Eclipse behavior [1]. I wrote a poem once on Facebook about how much I hated Eclipse, and to my surprise I found a website dedicated to hating Eclipse.

Normally I believe a bad tool is better than no tool, but Eclipse was just such an unusually bad tool. It's a benchmark of how bad open source tools can get. I give money to Jetbrains because I hope we never go to such a dark place again.
