What is interesting is that Nokia is calling the 800 a "true nokia device", probably to hide that it really isn't
Compal was thanked in the presentation. So I think the 800 isn't made by Nokia, but by ODM Compal.

Nokia also made a point that the speakers holes are drilled in the 800. In the N9 they are also, since the N9 is carved from a bigger peace of plastic. The 800 isn't, it is "injection molded", just like all the other mobile phones today. So either the production method for the N9 also had serious problems, or compal just couldn't use a similar production method.
The Nokia 800 is like a legitimately branded Chinese knock-off of the N9.

Also the Lumina 710 is like a replica of the Nokia 603, but with a nicer color selection.

The Nokia maps, and the radio mix is a way to fix the missing features for people coming from Symbian to Windows phone.
A shame that NFC isn't implemented in the phones, wonder if it isn't present or just not supported by software.
