Ok, but WHY ?
40% more chance of dying in the next 3 years, but WHY ? because the chair broke ?
They just did statistics and conclude that sitting is harmfull. Ok. But i'm sure we can also find that, for example, more men died than women. Does that mean being a man can kill you ?
I don't mean being sat most of the time isn't harmfull, but i mean this study doesn't PROVE anything.
Well, Eclipse is slow, crashes, has a lot of features but doesn't really do anything nicely (javadoc integration is damn awful tu use). More features doesn't mean better.
What i like about LighTables is that it seems to have few features, but do them well. It has a nice clean UI (even if it's just mockup, i don't think it needs anything else) and the UX seems nice too from what i understood.
Maybe what you didn't understood is that it's NOT an IDE for computer scientists : it's more aimed to visual programmer, webdev, or gamedev, creativecoders. People that want to do both design and coding.
BTW : i just trashed Eclipse, not anyone. I still use it because it's still the best ide for javacoding (even if i haven't done any in a while), which, to me, isn't really flattering for the state of coding IDEs.
