After 3 years in the UAE allow me to share the pluse deltas with you. Bear in mind that I would not dissuade you from coming, instead use the following to be fully aware of what you are getting into:
DELTAS:
* This is NOT a tax free country. The owners of the UAE have found all sorts of methods of taxing expats including Marina Municipality Tax, hotel service charges, etc.
* Expats are treated as second class citizens; something to be tolerated in order to get the country built. Do not expect the locals to be open or hospitable - i.e. aggressive driving/driving on the shoulder by Emeriates.
* Banking is difficult - do not expect a banking system that is customer friendly or easily accessible.
* Despite local claims, it does not treat everyone equally. Females should expect to be treated differently as compared to males - i.e. opening bank accounts without a male spouse is difficult.
* Asidse from the desert, there is little beauty. The cities are creations of people - not something that nature created.
* Forget "great" food establishments - you will miss restaurants with a heart/soul. No Ma & Pa restaurants.
* Blocking of basic internet services such as Skype simply to support locally owned communication companies.
Pluses
* It is very safe. Because the locals are very well off and the expats are here to work, crime is very low.
* If you love the heat, you will love the weather.
* Cheap gas.
* Great selection of produce.
* Most every food service can be ordered and delivered to your front door.
* Highway systems are outstanding.
* Easy accesss to the ocean.
Be open minded and remember that you are there only temporarily.
Good luck.
