Just five months after launching its first smartwatch, the Galaxy Gear, Samsung has unveiled its two newest wearables, the Galaxy Gear 2 and Galaxy Neo. Both the Gear 2 and Gear Neo offer significant improvements over their predecessor including an all-new Tizen-based interface, a more powerful processor and a heart rate sensor. Both watches will ship in April and, though Samsung is keeping mum on pricing, we suspect that they may be less expensive than the original, $299 Galaxy Gear.
