Digital Trends – This week, Nintendo launched the first major glasses-free 3D handheld device. If youâre wondering, yes, it has better 3D than either of these two phones. However, HTC and LG arenât far behind. While I have no love for LGâs implementation of 3D in the Optimus Pad tablet (T-Mobile G-Slate), LGâs first attempt at 3D in the smartphone space is a different story. The LG Optimus 3D does the third dimension justice with glasses-free 3D. And HTCâs new entry, like everything HTC seems to put out lately, is polished and worthy of attention. But which phone is the best and which offers the best 3D experience? I spent some time with both devices at last weekâs CTIA trade show. My findings are below.
