Samsung's finally launched the much-leaked Galaxy Alpha, a fancier-looking but stripped-down version of the Galaxy S5. As expected, it sports a substantially different, less rounded design than the GS5, with metal sides that gives it a glancing resemblance to an iPhone 5s. The Alpha is also much lighter and thinner than its big brother at a mere 6.7mm and 115 grams. Samsung said it took a "fresh approach" with the new handset's looks, something it vowed to do in the face of a steep downturn in sales. The new design could also give some clues about the look of the Galaxy Note 4, set to launch early next month.
