There is no need to spend top dollar on software such as Microsoft Office and Adobe Acrobat Professional for every employee when there are lower cost (even free) alternatives out there that will satisfy the needs of 90%+ of users.
MIcrosoft Office - why do all employees need the full suite purchased when all they need is Word or Excel? Dump the cost and go with OpenOffice or IBM Symphony (free).
Adobe Acrobat Pro: Why pay Cadillac prices when there are other alternatives which are cheaper and provide the functionality required by 99% of users?
These are just a couple examples of useless software spending that is not required.
NOTE: Open Standards is NOT the same as Open Source.
