Juts tried it on my Lenovo X300 ...
At the installation you can create ZFS filesystem, but only with on disk and only with one dataset ... useless.
Also after reboot it detected GeForce FX 5500 ... (dekstop card in laptop?) and attached
vesa driver to it (so why they yell so much that they have binary nVidia blob even with amd64?) ... while I have Intel X3100 ...
I would consider that 'release' as BETA and wait for 8.1 or 8.0.1
... but I liked the splash screen
