I discovered Haiku in 2013 but only recently I decided to give it a try. I downloaded it and tried it in Qemu and VirtualBox (different computers, laptop and desktop) and I fell in love with it (especially how smooth it runs and how nice and clean the interface is). Then I tried booting it from USB and it worked pretty well except for 2 minor inconveniences (unsupported BCM4312 and touchpad only recognizes left click). I have no complaints about it and I’m just waiting until my WiFi card is supported to install it on my hard disk, meanwhile I will continue occasionally emulating it.
To the devs and other contributors: thank you for making this awesome operating system.
