Gadget Ogling: Curves and Edges, Toasty Toes, Smart Charger and Dumb Wearables

Welcome to the latest installment of Gadget Dreams and Nightmares, a weekly look at just-announced personal tech items. There's plenty on the menu this time around: Samsung's latest smartphone and tablet salvo; two pieces of smart, on-the-go tech; some curved home entertainment options; and wearable devices from an unlikely source. As ever, these are not reviews, and the assigned ratings aren't a tacit opinion on each product's quality -- instead they reflect my interest in using them.
