Im sure a lot of people feel that USB conveniently meets their data transfer needs. But Thunderbolt does the same job at a significantly faster rate. Maybe its ahead of its time, possibly people are reluctant to adopt a new standard, or perhaps it targets a totally different market. Apple has added it to its new notebooks so there must be really something special with Thunderbolt. https://www.eetasia.com/ART_8800647510_499495_NT_c184c09a.HTM What do you think?
