Haiku OS (http://www.haiku-os.org/)

What's your opinion on it?  I've been using Windows since Win95 and I'm currently using Win7 and Ubuntu 10.09 (Oh shit, 10.10 is out now) so will there be much of a learning curve?  How is support?  Yeah, I've Googled it.  Having problems finding reviews not on their own website.

get a mac. i have 10 different operating systems running on my mac in parallels, and mac os x is still by far the best one. in order of goodness: ubuntu, chrome os, open solaris, [insert 9999 operatign systems here], windows xp/7, [infinite number of operating systems later], windows vista
