Shanghai and Beijing - Some differences

People are always comparing these two cities.
A few things which I saw were:
BJ is large SH is smaller
BJ is almost as cosmopolitan in comparison to SH
BJ is definately more cold in the Winters (Somebody told me it was -20 for two days this year (2010)
People love to chew thier Mandarin in BJ. Use a lot of Nar and Zher which in SH will be Nali and Zheli which makes the chinese a bit more difficult to understand.
There is much more to be seen in Beijing . the Wall , palace etc. In SH there are only pubs and restaurants
SH is more fashionable
2 tier hotels are more contemporary in SH . I was staying in a hotel called Winterless Beijing in the CBD area of Beijing and it was so cold(in way of service and decor) that it should have been called "Summerless".
There are more organised queues for taxis in SH.
