I was on a beta version of elementary OS a couple months ago, and it was like a breath of fresh air.
elementary OS sets out to settle the number one complaint casual users have of other Linux distributions: design. Other Linux distributions look like a mish-mash of a bunch of different designs by many different people. elementary OS has a beautiful, striking, and (most importantly) consistent vision driving the look and feel of all its applications.
The only thing that previously kept me suggesting elementary OS to people who don't normally use Linux was its instability as a beta release. If this release is as stable as I hope it is, then elementary OS is without a doubt the best distribution to introduce new people to Linux.
I think the following quote pulled from an update on elementary's website defending some unconventional decisions they've made[0] illustrates best what they're trying to do:
We know there are many traditional Linux users out there exclaiming that Linux is all about choices and we should make everything configurable because that’s freedom. But that isn’t why most of you are here in the first place. You’re here because we’ve been making choices for you. Lots of them. We always have and always will. We’re the open source OS with opinionated design. That’s what makes elementary so good. We trim the fat. We optimize. We organize. We rethink.
That's an attitude that's sorely missing in the Linux community. elementary is tackling hard problems and succeeding.
I look forward to the the success of elementary OS.
