Launched with much fanfare at the E3 gaming expo in 2009, the PSPgo was supposed to be a major refresh for the PlayStation Portable. It did away with the UMD (Universal Media Disc) format used in previous PSPs in favor of a sleeker look, but that meant gamers couldn't play titles they already owned. And because it was more expensive than previous PSP models, many gamers saw no compelling reason to upgrade. A recent price cut may stimulate demand, but at this point the PSPgo rates as one of Sony's few gaming flops.
