The PSPgo is the latest PSP model from Sony, released on October 1st 2009. The PSPgo is the smallest and lightest PSP yet, weighing in a just 160g. It’s 50% smaller and 40% lighter than the original PSP (PSP-1000). We’ve been playing with the PSPgo for a couple of days now and though it was about time we share out thoughts. In short, the new model is great but there are a few short-comings.
