Three months after Nokia announced its N900 smartphone, the device has arrived in the United States.

Confused by Nokia's dual-platform, Maemo 5 and S60 5th Edition smartphone choices?

According to The Really Mobile Project, Nokia will drop S60 from all of its flagship N-series consumer devices in favor of Maemo.

The Nokia Blog has what it claims is an official response from Nokia on this delicate matter. As you'd expect, Nokia says it remains "firmly committed to Symbian as our smartphone platform of choice." It then added this little gem: "Maemo is our software of choice for devices based on technology that you'd typically find inside a desktop computer. It delivers a different user experience and enables us to widen the market we can address."

Furthermore, Nokia will first run its Maemo app portal, Maemo Select, alongside Ovi Store (Symbian app store), but plans to merge them into one later on. While we’re thrilled to see more Nokias on the powerful Maemo platform, running two mobile smarpthone OSs and two separate app stores will definitely cause confusion to the customers.
