What do you think about new Particle system? 

Will you acualy use it and how?

I was playing with different way to use, you can check at youtube : http://www.youtube.com/playlist?list=PLaH1PMiI_7AhaKodSD3QgQY38a4JH7Yz-

and found it intresting, but personaly, i think 360 ecosystem is bigger impact on my future work.

Particles are an old request from users e-on listened to. I don't find this terribly useful, and it doesn't seem to be fully implemented yet, since there are no full dynamics involved, besides effectors.

Ecobrushing to me, is a lot more interesting and useful.

360 degree ecos and ecobrushing are fairly easy new elements to get a quick win from. 

I think we're going to need to spend a lot more time getting to grips with particles and materials on particles before we can really judge them.  Just getting each of the effectors to do something has taken me a week!   In the usual Vue way I think we'll start to learn from each other pretty quickly and before you know it we'll have something new and powerful in our toolkit.

Having the same experience. Being at the bottom of a learning curve scrapes.....

The one thing I've tried so far turned out great. The particles for fresh snow on the ground and objects looks far more real than I could do before. I'm hoping for equaly good results for things like smoke and dust.

I'm one of those who asked for this and I'm happy about it. I imagine they will add to this in future versions to make it more akin to particle systems in other packages. I'd like to see a better way to deal with fluids. To me in environment software things like particles, fluids and the like are a no brainer.
