I mentioned both of these in other threads, but...
I'm very tempted to pitch in for this, despite not owning a single bluetooth device at this point in time.
Pro Pinball (!!!)
This is what made me register a Kickstarter account (until then I'd only chipped in to ones with PayPal options). I've wanted to see the Pro Pinball tables updated for years (mostly to get all the physics enhancements of the later games into the earlier ones, but also to get around some of the issues playing them on modern PCs); so this is one of my dream remakes, and supporting it was a no-brainer.
That said, I don't really agree with the pledge/reward levels they've come up with -- it strikes me as too much like final retail prices, given that they're asking people to fund the development. I also suspect their timeline is naively aggressive for the number of platforms they're intending to support, unless they've already done a heap of work to those ends. I'll be a little surprised if this one succeeds to be honest, but if not then I'm hoping they make another attempt, and that they can make it happen.
