3. Thumb drive
The humble thumb drive. The most nondescript, modest-looking device in the world is made by Singapore-based Trek Technology.
At the end of 2000, Trek Technology partnered with IBM to sell the first USB flash drives with a storage capacity of 8 MB commercially. Sadly, Trek Technology's patent rights were violated with little thought when rival manufacturers started to make their own to sell. Lawsuits were filed to get them to start paying royalties, which worked in Trek Technology's favour.
Who would have thought something so simple and useful could have originated from Singapore?
