Tracker is very refreshing for me as a spatial Nautilus enjoyer (and it even work right across workspaces!).
A very well thought out and executed environment.
Trackpad/TrackPoint works.
LAN works.
Wifi works.
Graphics are accelerated (integrated GPU).
Some function keys work.
Speakers work.
Didn't try suspend/sleep/hibernate, HDMI, Thunderbolt, headphones, SD Card.
WebPositive seemed to hang when I went to SoundCloud.
WebPositive, their own webbrowser, isn't great, but there are many acceptable browsers (mostly webkit2 based) available in the package system.
Recently, the developers got Firefox working, but that one isn't available as a package yet. Soon.
Hope Haiku continues to grow as an alternative OS that can do more daily driver activities. One day I hope Obsidian can be ported to it.
I often wonder where we'd be today if Microsoft's illegal activities had been stopped soon enough for Be to survive. BeOS really felt way ahead of its time.
Having tried Beta5, I am convinced I could do just that.
It has got working ports for e.g. modern webbrowser, multiple IDEs, openssh, libreoffice, caligra, gimp, inkscape, krita, wine.
