Loved and hated my Nikon V1 [RIP...]. great images, fast enough AF, awesome with the FT1 and 300/4... but a terrible control set that seemed designed for non-photographers.
Wasn't a fan of the Sigma DP1, just never got on.
Canon SX40 or whatever it was, excellent zoom but 1/20 images nailed focus at a useable ISO. Still have a soft spot for ultra zooms [I have a P900 purely and only ever used at 2000mm like a spotting scope] but couldn't get on with the Canon.
Still, on Flickr there's plenty of evidence that I'm the worst bit of all the equipment I've ever owned..
