There seems to be a lot of deliberate misconceived information floating around regarding USB 3.0 versus Thunderbolt.
Pundits making statements relating to consumers not needing the fast connection Thunderbolt has to offer are simply wrong. Thunderbolt does in fact provide the ability to operate high resolution displays such as the new iPad 3 retina display directly. Such hi-rez displays require maximum bandwidth to operate at maximum efficiency (pity the poor souls who purchased iPad 3 minimal spec tablets).
USB 3.0 requires a separate graphics card to transmit the data from USB 3.0 to the actual HDMI or DVI port. we are speculating this will be a lot more expensive compared to a single Thunderbolt cable. This is nothing new as Windows based computers have tended to require more peripherals to run graphics than Apple based computers. One normally purchases am Apple product that is extremely efficient straight out of the box
currently a standard Thunderbolt cable costs approximately $100 U.S and a USB 3.0 cable is roughly $15.00 so the debate can turn into a price war until of course prices drop on the Thunderbolt cable which it most probably won’t for some time due to the fact there are digital components stored at each end of a Thunderbolt cable.
Thunderbolt does have extra bandwidth to offer. It’s able to effectively remove the barrier between peripherals that are connected inside a computer, and external peripherals that you can simply plug in.The transceiver attaached to either end of a TB cable allows daisy chaining & the ability yto connect to optic fiber cables. This in essence then allows the transmission of data over long distances rapidly.
So the debate continues, which cable will become the benchmark for future tablets ? It will boil down to which cable the public utilises more. Apple Thunderbolt definitely has its merits boasting loads of applications and more and more companies such as Sony supporting it but USB 3.0 is cheaper and already has a familiar cognitive understanding with so many consumers who simply want something that is easy to use and simply does the job.
