If you or your kid wants to learn how to play the piano, then consider this bad boy: the One Smart Piano. Available in this $300 keyboard and a $1,500 full-size upright, the One connects with your phone or tablet to smarten up the piano-playing experience.
The same goes for the keyboard settings, most of which don't exist in physical form like they do with most keyboards. Instead, they're relocated to the app. They're comprehensive, but again, kind of hard to find at first.
At $300 for the keyboard model and $1,500 for the full-size upright (roughly £205/£1,025 or AU$390/AU$1,965), the One Smart Piano won't come cheap. Read our full review for our full, hands-on impressions.
