The basic model missed out on WiFi, it had a smaller hard drive, and it didn’t have a multi card reader like the premium did. But other than that the two models were actually very similar. They both had 4 USB ports compared to the 2 you get on all models now and, crucially, in the US both of the launch versions had PS2 backward compatibility. This means that at the time Sony thought backward compatibly was important enough to even fit on the base model."
