Do not post what you know NOTHING about. The N9 is based on code that has been better tested than both Android and the iPhone, and not compared to MS WP. The core software is Linux, which is also very similar to MacOS (Unix BSD). The main difference to the N900 is how the frames are drawn and the colour used. Nokia made the N9 to comply with a project they had with Intel, and Samsung has made a prototype of a similar device. Finally: who are the "Big boys"? Look at the mobile handset market and tell me where the are the "Big boys". Android is a shot at a simplification of the same OS.
