I guess we'll just have to wait until someone has seen and played them. I too heard the Giovanni clip. I think Gio could probably make a rock sound good, so I'm still skeptical.
Suck it up and keep carrying your drums for now......unless LP's come up with an engineering marvel, I doubt that the mobility will make up for the loss of the shell.
Is mobility really the point? Come on now, I'd haul a heavy drum if it was easy to play and sounded great. If the compact conga sounds (or feels) even marginal, will you give up hauling a drum that sounds like a real conga? I won't. The conga (and drums with shells) have been part of music forever. I would guess that these drums will be relagated to the bargin bin with the '80s vintage Miami Vice theme roto-toms.
Personally, if it's a good practice pad, I might buy one for my office. However, even after hearing Gio play one, I'm not willing to give up my bass tone and the resonance of my shells when it comes to gigs. A snare drum stand and a compact conga isn't going to save you much space when you've set up to play, so the only thing this compact conga is giving you on a gig is mobility. At what cost? Isn't the goal to sound good and to do the instrument justice? (Okay, maybe that was a bit melodramatic, but I'll leave it there anyway

)
I've bored you with my opinion. If you disagree, that's fine. Enjoy the drums if they make you happy.
