I think the guitar is awesome, but the piano is just so...beautiful. The guitar doesn't move me as much as a piano does.
When I pick up a great Taylor, Ovation, Martin, Takamine, or any solid spruce top guitar, it sings to me. It's very sensual. I loved my all mahogany 1947 Martin, and that thing had soul for miles. It can move a person as well as a Steinway well played.
But the mechanical is also sexy in its own right. I was a techie for 8 years, so I appreciate silicon and motherboards, and any electric through a well designed 100+ effect digital multi-effects rack is really cool, too. Mechanical in every detail, but so well designed.
I liken my 1947 aged Martin to a nice hot air ballon ride, beautiful and memorable, and I liken any electric going through a high end digitech or rocktron multi-effects unit as rushing through the sky in an F-18. Both are great for what they are. I know that the 100+ multi effects unit is sterile, but it's cutting edge and fits those moments when I appreciate that.
When I go to a car show, I split my time between pre-1920 vehicles (Concours show) and the latest that Ferrari, Porsche, Acura, and Lotus have to offer with onboard computers, great performance, great gas mileage, and IP protected composite materials not even seen by NASA.
