PSP
The handheld was incredible for its time because of all of the additional functionality it provided. See when the PSP came out, we didn't have smartphones that can do everything that we have today. We had blackberries and windows phones that were mainly used for IM than general media consumption. We also had things like ipods and Zunes that could play movies and music but they couldn't do any web browsing or play games that you wanted to play. And the video experience was pretty meh.
The PSP combined so many functions together. You could play great games, you could watch movies in a wide screen format, you could play music, you browse hentai on websites. It was an incredible piece of tech for its time.
