Well, for me that was the case, the first two days I loved the 16", and I know it's a better machine, then I realized I wasn't using it as a laptop as much as I did with the 14" due to its footprint, even around the house, but you have to be aware I've been using 13" form factor since 2008-2009, not exactly the same kind of change you'll be experiencing, that's why I'm settled with 14", but that's just me.
Hence the reason I think you'll be more used to the bigger shape/size given you're coming from a 15", so the footprint shouldn't impact you that much as it did to me. And yes, I do think these things have to be tested more than in-store, cause you can't understand proportions 100% with those big tables or how it will fit in your house/backpacks/etc, kinda similar as with shoes, you try them at the store, they're super cool, then 2 weeks later you realize that they don't adapt to your feet and/or are not as comfortable as you first tried, then you wish you could change them, but again, that's just me.
