Windows 7 on Dell Inspiron 1440

I had a friend who wants Windows 7 tried on her on her Dell Inspiron 1440 laptop. The laptop have the following specification:

I installed Windows 7 Professional on with other softwares.

The installation works fine and all the device drivers were supported by Windows 7 except for the bluetooth application. So I need to go to the support  center of Dell Computers to download the necessary software.

I like this laptop. Its fast, elegant, and have a good battery.
