Something truly unique on iPad
So I bought a new iPad on the day of release, as my first tablet. So far I've been completely...underwhelmed. I know this is something awful, but so far it really does feel like a giant iPod Touch. I've tried many of the recommended "must have" apps and have come away disappointed. Flipboard, Pages, GarageBand Swords and Sworcery are all things I can do on my iPod Touch already (or find Android equivalents on my Galaxy Nexus). Reading books, comics and magazines are all things that my phone's screen is large enough to handle already, and more do them more conveniently. I've heard that music creation is nice, but I'm not terribly interested, I'm underwhelmed by GarageBand and other apps generally cost $15+.
So, my question is what's something completely unique to the iPad (or tablets in general for that matter)? Something that really can't be done (well) on my iPod, Galaxy Nexus or PC? What really justifies this purchase?
