it is sony's technology, developed and originally manufacturered soley by themwozzaa said:Doesn't matter which one you buy really there both technically rebrands. They will both have the same internals same memory chips etc. I dont even think its sonys own technology to begin with they just bought the rights to it same as sandisk probably did.
Personally though i wouldnt buy the sony one when i know that i can get the exact same thing for cheaper just without sony wrote on it.
