As no x64 and apparently not in near future either, I say: Nah...
This almost made me decide against picking it up as well ... hard as it is for me to resist any unique plug that's available at an 87% discount.
But I downloaded the manual and read about half of it. There is some seriously brilliant inovation in this thing. Even if I never used it for anything other than playing around with on a rainy day ... well, let's just say my wallet just got 20 bucks lighter.
I don't think the product web page does a very good job of presenting just what this thing is and does. But a quick read of twenty or so pages of the documentation (maybe about a third of the total pages) should give anyone a decent idea.
