Similar to the way Microsoft offer cheap software to employees of companies with licence agreements - NHS staff or contractors can get cheap Office software. The scheme has now been extended to include Office 2008 for the Mac - see announcement below.
To get this you will need an nhs (or nhsnet) email address.
Office 2008 for Mac available from 1st April 2008
We are pleased to announce that Office 2008 for Mac will become available at the extremely advantageous price of under £18 for NHS staff as part of the Home User Programme.
The offer means that NHS staff can buy one licence of either Microsoft Office 2007 or Office 2008 for Mac virtually for free for home use. Additionally, if you had previously purchased Office 2004 for Mac under this scheme, you are now entitled to order the new Office 2008 for Mac as long as you destroy your existing copy of the previous version.
