Apparently the oddly-shaped OreObject SPHEREtouch mouse was successful enough for another go-around, as the luxury computer accessory maker has announced a follow-up called the SPHERE 2. Just like the original, the new version features a horizontal scroll wheel on top and two touch-sensitive buttons, but it adds 3-stage instant resolution adjustment, a detachable Micro USB cable, and a new 24K gold option. Vertu owners looking for a mouse to match their phone can pre-order the SPHERE 2 online starting at $185.
