In Pictures: Hot or not, 10 tech trends for 2013

NOT: Windows RT tablets

You know your new hardware platform is in trouble when Samsung declines to make one. The South Korean electronics behemoth makes every kind of device for every mobile OS known to man (except Apple's, natch), but it's taking a pass on RT, as are HP, Sony, and Toshiba. Meanwhile, Acer delayed shipments for six months to see if anyone is actually buying these things. What's left? The Asus Vivo and Microsoft's own Surface, which comes with its own version of Office but isn't compatible with most other Windows 8 applications. Get yours now, before they become a collector's item.
