I'm typing this from OpenSolaris 2008.11 and I'm actually surprised how "desktop-friendly" Solaris has actually become. The default GNOME-based desktop is gorgeous and works well. Hardware support may not be all that broad, but when hardware is supported it's REALLY supported: even booting off the live CD, my Atheros wireless card, NVidia 3D card and crappy on-mobo sound were "auto-magically" detected and set up. Performance is also quite snappy, even on my aging Athlon XP 3000+ with a measly 1 GB of RAM. In short, OpenSolaris is more than up to the task of working on Toshiba's new laptops.
