C'mon, thinskins!
AX1000 (if realized, as in put on amigakit for actual purchase) will be pretty cool.
Sam 460 looks pretty cool as well.
MacMinis with MorphOS already are cool (already as in they are already "in the wild").
Aros has potential to be cool.
Classics? ... well...classics are classics

there is always a dark side:
MorphOS: runs on Macs, has wonky licensing scheme
AOS4.X : Hyperion. That's enough.
Classics: We ain't getting any younger. Oh, and Git offah mah lawn!
Aros: Can someone say alpha?
All this bickering is the power of the one (MS) ring. Fight its influence!
You want the most NG bang for the buck? No brainer - go MorphOS (Or Aros, if you're good at debugging your own).
You want the most and have a pure "It's my own, my only, my precious!" attitude about the hardware? Easy! Go Classic

Naah, just joshing - get a SAM.
Wanna dink around and see what you can do in 2M of chipram and a handful of fast? Classic all the way, baby!
