I have to say I agree with Ash - There is no need, my profession is in IT and has been for over 30yrs, and in many instances it can be beneficial, automating process, removing manual error, consolidating and virtualising, data warehousing etc...
BUT I have also seen a lot of examples where it (IT) has been used, for use sake and doesn't improve or solve anything, as with all things in life just because you can doesn't mean you should....
Just my opinion of course and opinions can be wrong too ;-)
