App Categories Like Virtual Music Instruments May Get a Second Wind on the iPad

I’ve been fascinated by the emergence of unexpected iPhone app categories like “amusing entertainment” (iFart & Koi Pond) and social music creation (Smule’s Ocarina and I Am T-Pain) since iPhone apps first appeared in the summer of 2008. I’ve been especially interested in the virtual musical instrument app category. Some like Ocarina literally seemd like a perfect fit for the iPhone’s physical size. Others like guitar and piano virtual instruments were also well done.
