Picking the right version of Office 2007 will depend on your business needs.  Some of the areas that are beginning to concern and interest companies when it comes to their next Offiec 2007 purchase are:

  • Information Rights Management (keeping your digital secrets, secret)
  • Content Management (workflows, sharepoints, reports etc)
  • E-Forms (using InfoPath to capture data and organise it)

There's a good site here which helps break down which features you get in these areas depending on the vesion of Office you go for.  Well worth checking it out before deciding upon your purchase.
