I think things have changed quite a bit, display driver problems mostly disappeared when vesa support arrived (abet unaccelerated), and ac97 provided support for basic sound cards. The bigger problem today is the lack of a modern web browser. There have been many attempts from fgb's abaco, updates of mothra, chyron (sp?) from inferno, and cinap's linuxemu wrapping around opera. Sadly none of these works well enough for me to mean I can live without another OS. My current solution at work is a windows laptop (shut) with a raspberry pi running plan9. I use remote desktop to the windows box for web browsing and a some other company stuff. I develop code for a living and regard plan9 as my IDE. I still love the interface, and my fingers know it well. I have a file/cpu/auth/dns/mail/cifs server at home running plan9. But I also need a Mac and several ipads for me and the kids. -Steve
