Some years ago (in 2005 or 2006) I always ran the latest E17 builds as my primary desktop environment. I really liked it! Some things about it were awesome, but OTOH it always was a little bit incomplete. It just took too long, because in 2006 I bought a mac and moved away from Linux.
On my current laptop I had Linux installed for a couple of months, but I didn't try E17 anymore. It just was too late, I didn't want to go through the checkout/build/install stuff again. And now I have removed Linux completely (again), because an Ubuntu update took four days, and after that my mouse didn't work anymore.
Anyway, congrats to the E17 team! I still think you have a great piece of software there.
