Is the new, slimmer PSP all that different from the original? It may be hard to see at first glance, but direct comparisons show that the system does, in fact, come with a number of significant changes. One can easily see that it has an even glossier look (fingerprints beware!). The system loses some girth all around, but there are a few other more interesting changes to note: the never-used IR port is removed, and the standard battery pack is smaller (how does that make battery life longer?).
