Disclaimer: I'm an owner of the v1.0 so my opinions are a little bias. I like the blades, I especially like the fact that it doesn't use 12VDC but it looks a little too, uh... Star Trekky? The sample colours don't help, but all I see is a phaser or a new Federation ship.
I prefer the roundness of the L wire (sp?) It gives the Snack Bar a more nostalgic look, more tubular. It looks more like retro neon tubes to me and therefore has a more appealing and realistic look. The blades make it look more futuristic and that doesn't match the 50's feel of this pin.
Of course I'm an old bastard so I'm probably in the minority.
