ASUS has big ambitions with its PadFones, a unique phone-to-tablet convertible concept that was first introduced back at Computex 2011. While these devices are barely nibbling on the global mobile market (let alone entering the US), the company still stands by its "N+1" philosophy: "to add on a simple change which allows the product to evolve beyond its current capability." This is evidenced by its five iterations of transformable phones, including the new PadFone Infinity (A86) and the upcoming PadFone Mini. The question is: when, if ever, will the PadFone break out of its niche? CEO Jerry Shen reckons now is the time. What's more, he's going for a dual-series strategy, henceforth, with a high-end line for Europe and the US, and a "mainstream" line for Asia.
