It's tough to say when, or if, the heralded USB port will ever be truly replaced in the eyes of the masses. But Thunderbolt is sure working towards becoming a great secondary option, if not an outright replacement in time. At this year's NAB Show in Las Vegas, Intel announced Thunderbolt 2
. It's the latest edition of the high-speed transfer protocol, with a bandwidth boost up to 20Gbps.
Moreover, there's the addition of Thunderbolt Networking, which effectively acts as a crossover cable in order to allow two computers to directly connect
and share information over a high-speed superhighway. Thunderbolt Networking, emulating an Ethernet connection environment, provides 10GbE throughput between two computers. OS X Mavericks already supports it, and a PC driver will be made available "soon" in order to link two PCs together or a PC to a Mac.
The industry-wide support for Thunderbolt 2 is impressive. That's the kind of progress that'll be necessary for it to succeed in the long run, and get in front of more consumer eyes.
