Is there a downloadable user guide? Did I miss something somewhere? Something (maybe w/ pix/diagram) to remind me of what each button does & what settings to do for what & so on. I'm migrating from a 2nd-gen-SE. PDF would be nice. I don't see anything in the iTunes store, and I'd prefer not to/shouldn't have to pay bigbucks for it. And going online to support for every question is {unladylike-language-here} bj ?
