SAMSUNG’S $2,899 TRIFOLD PHONE Samsung’s new Galaxy Z TriFold will launch in the U.S. on Jan. 30 for $2,899, making it the most expensive smartphone on the market. It unfolds into a 10-inch tablet, is ultra-thin when open, and supports 200,000 folds. The device will be sold only through Samsung, not carriers, and comes in one black 512GB model. While praised for its large display, it’s heavy, bulky when folded, and its software feels unfinished for the price—making it more a luxury showcase than a mass-market product.(*Walter Bloomberg)
