Dear All,
I bought New Nokia Lumia 800 on 18th Nov 2012 in Chennai... I feel that the phone looks good and design are great.. But it is not user friendly... Please find my Input... If I am wrong, please correct it...
Pros 
- Good design
- Fast Access than Android device
- Clear Sound and loud speaker are also good...
- Headphone are grit...
Cons :
- Battery life
- Camera is not up to the mark...
- Business card can't support
- We are not able to set a favorite songs as a ringtone...
- We are not able to transfer Documents (Word/Excel) directly from PC to Phone...
- Zune software are support only Media files...
- Contacts are synchronize through windows ID... (Hot mail Or Live ID) only not through Nokia Suite... It is a big minus for Lumia series... We need internet to Synchronize our Contacts...
- Windows live ID can support only CSV format for contacts... It is a tedious process to convert your Contacts (Vcard to CSV)....
My suggestion is If u are really impress with Lumia 800 and you are sacrifice the above said information in Cons section, then buy this phone otherwise go with other device...
Regards
Krishna Prakash
