AROS has the same limitations until today.
I was alsa excited, when discovered Haiku, but... it was two years ago and almost nothing changed since that time. They do their work really slowly due to the fact, that they receive some ca$h, and Google also support them. Last time, when I tried it, it was very very slow on my laptop and after restarting the installed Linux was also very very slow. Just a battery removal helped.
