None of my clients from schools, charities or not-for-profit organisations can use it.

I'll load NeoOffice onto their computers for them, they'll be very happy with that I'm sure. Last time I tried it, NeoOffice was much more stable than the official Office anyway. It has been able to open corrupted Word documents for me on a few occasions (Word corrupted its own docs somehow and was unable to read them, but NO worked just fine, reminds me of how Adobe Reader can't open some of the documents that Apple's Preview can open without issue)
