"The first GPS device I reviewed for TrustedReviews was a Mio product, the
Mio 168 and was notable for being the first PDA with integrated GPS. Since
then, GPS has very much entered the mainstream and is now one of the hottest
selling technologies around. Whereas GPS used to be a technology that was
piggy backed onto PDA, it’s now most popular on dedicated in-car units which
Mio refers to as Personal Navigation Devices."
