1up has a feature revisiting the ongoing struggle for supremacy in the handheld market. The PSP and the DS have had many ups and downs in the past year, and the column lays out the successes and failures for both systems. From the article: "And then there were two. The DS is cleaning up in Japan -- the sheer demand for the console there has siphoned every single unit from the marketplace, while PSPs sit unloved on store shelves. But here in the U.S., it's a neck-and-neck race. And, since the PSP launched one year ago on March 24th, 2005, we thought it'd be an excellent time to revisit the past year and gauge the situation as it stands today."
