The first thing that appealed to me about Sabayon, not only that it's a polished Gentoo distribution (aka geek, aka exceptional) is it's refined selection of applications, essentually the best pick of the litter.
Considering M$ Vista ships with pretty good voice recognition
support, beyond what's available in the FOSS (to my knowledge), Dasher, although a little tedious for the able bodied, together with Roborealm
could make your linux distro more interactive.
For my love of all things Linux and of course Sabayon, good old M$ is stretching heavily ahead with it's productivity applications. One only has to look at Office 2007 and Open Office for a quick blast back to 1980 computing. I think dasher could be used in correlation with other tools but fear it's a stretch from matching the productivity of the likes of Office 2007 and voice recognition. Natural voice
alone would be nice as an upgrade to the somewhat dated speech synth in FOSS distributions.
Think I'll search the forums for a comparison collection of productivity tools and add my five cents.
Windowz.. Cos the kids love it!
