Hello all:

MS renewed his windows all the time, ...2000, XP, Vista and w7. Simultaneously, Office 2000, 2003, 2007 and 2010.

I am not passionate at vogue, particularly the OFFICE. Up to this moment, I am stiil using Office2003. On the other hand, I am afraid to be lag behind and miss some precious functions.

Could you tell me your experience about the upgrading from office 2003 to 2007 and 2010. Is it necessary?
