I chose to buy a Leicaflex SL kit rather than an Olympus E-P5 or Sony NEX 6. Why? Because I already have the GXR-M, and when I acquire a Leica M(240) in a year or two, I want the longer R lenses for it. The GXR is more than just sufficient until then.
I didn't buy another Hasselblad lens either. Because the SWC, the 500CM + 80 + 150 are enough.
I didn't buy a couple of Guggenheim Museum mugs either, but I just might order them on line as I think they're cool looking.
I didn't buy the James Turrell book at the Guggenheim, but I might just order that on line too.
I didn't rent a car while on this trip. I borrowed an old Mercedes 350SLD (or something like that) from a friend. I love it, driving it feels like piloting a medium sized yacht and the 350 Turbo Diesel sounds like a watercraft engine too. My brother wants to record it for backdrop sound in his latest video production.
There is an infinity of things I didn't buy.
