The latest update of the Roku media player, hitherto known as the Roku 3, features a number of welcome refinements over the cheaper Roku 2 and entry-level 720p Roku LT.It offers wired and wireless connectivity and a much faster dual-core Broadcom chipset. In short, it's the best built Roku player seen to date, but it still has foibles.A cursory glance might suggest that nothing much has changed in Rokuville.This new player is still a glossy black puck, although with slightly less girth, at 90mm across. In situ, it looks like little a futuristic pebble sprouting cables.The distinctive Roku fabric tab is still in evidence and there's a tiny status LED which glows when the unit's on.While the Roku 3 has integrated dual-band Wi-Fi (a/b/g/n compatible), the wired Ethernet option is invariably the best choice when it comes to streaming.
