Sony says it has shipped 10 million Portable PlayStations in the product's first 10 months, in a press release. The PSP has now shipped 3.00 million units in Asia (launch date in Japan: December 12, 2004), 4.47 million units in North America (launch date: March 24, 2005) and 2.53 million units in Europe (launch date: September 1, 2005).
The "attach rate" is somewhat less impressive. The press release says:
On the software side, PSP Game software shipment has reached 19.6 million units and 183 titles have become available worldwide as of September, 2005. Market for the UMD Video software titles have been expanding and cumulative production shipment has exceeded over 15 million units as of September 2005.
These are early days, but on average that's only two software titles per user, and only 1.5 movies. And that's shippped, not sold.
