Windows does not include Office (MS Word/Excel/Access) but ou can buy a student version of this cheaply as a seperate item as mostly its not included.
Bluetooth....do you want to connect to you mobile? if so get a dongle at about £25 later.
Wireless ..... again if there is an access point you can wander about.... if not you will still need to connect the wires for the intranet/internet.
Pentiun M is the new mobile chip with a much larger on board chashe memory .... in otherwords its faster and uses less power. The 1.6 is arround the equivelant of a 2.4 pentium (if I remember correctly.
As for the laptop I recently got a Sony..... but then its for presenteations to customers..... the name / looks and 16" screen impress...... and I must admit it is a great laptop.
