Samsungs latest takes on wearables, the Gear 2 and Gear 2 Neo, were among the flurry of announcements from the electronics company at Mobile World Congress this year. Representing a refinement on last years Galaxy Gear, the Gear 2 and Gear 2 Neo are thinner, lighter, more comfortable and longer lasting than Samsungs first attempt. Both watches offer significant improvements on the outside — they are more comfortable to wear and provide the option to change the wristband with a standard 22mm watch strap, something that the first Galaxy Gear couldnt do. Samsung removed all of the electronic components from the wrist strap, so the camera (on the Gear 2), microphone, and speaker are now on the watchs body itself.
