Wow! it's been a year since a bought my Playstation Portable and I never thought that it was already it's fifth year last March 24, 2005. For me, this is the best gadget I ever had simply because it's Portable - you can bring anymore - you can play music, movies, games and even connect through the internet with it's wifi features.
The Director of Hardware Marketing John Koller had the following to say:
“March 24, 2005 will always be known in PlayStation history as the day we debuted the PSP systemin North America. At midnight launches across the country, hundreds of you waited with great anticipation in lines at local retail stores for the PSP system. With its best-in-class, 4.3 inch high-resolution LCD display, vast library of software titles and built-in wireless communications, the PSP system was the first integrated handheld entertainment system to introduce console-quality gaming and comprehensive entertainment capabilities to the portable market. Half a decade later, PSP is still going strong and continues to provide the best portable gaming experience and offer incredible value to consumers.”
