Upon first glance at using Haiku(nightly 51782) the past few days, my impression is that it is a sleek, modern operating system. Why? Because it looks, acts and feels almost identical to my favorite 90's operating system. Which by my best estimate, was at least 30 years ahead of its time. By that standard, Haiku still has plenty of time to develop and maintain relevancy as a modern OS.
Let's look at the big 3: Linux, MacOS, and Windows. For argument's sake, lubuntu, Ubuntu's lightweight twin sibling, is my Linux comparative. None of these operating systems come anywhere close to the responsiveness, architecture, and potential that Haiku has as of writing this today.
I've been watching Haiku develop from afar for a number of years. I used to be active in the community a long time ago. I even attended WalterCon 2004 in Columbus, OH and was present for the the unveiling of Haiku's name. My hat's off to everyone who has stuck with it all these years, and cheers to those who've joined the community since then. I'm extremely excited to be back. meep meep, ribbit
