Gotta bump this thread. The 2015 Pixel has been awesome on our Hawaii vacation. Been here five days so far and haven't been let down a single time. This thing is quick, light, agile, and just a beaut. Highly recommend.
The question you need to ask yourself (as I asked myself the same): what do you really need on vacation? For me, the answer was "the internet." What's better for the internet than the Pixel?
Hint... Nothing.
