IT Portal reports Two thirds of businesses still run Office 2007.
Spiceworks found that:
… 82 per cent of businesses in the UK, US and Canada are still using older, on-premise version of Office, with Office XP, Office 2003 and Office 2007 being used. Office 2010 is most commonly used, 43 per cent use Office 2013 and 17 per cent run Office 2016.
As a developer, I have one computer that still runs Office 2007 because I may end up writing a .net program that needs to access that version.
As to other companies using Office 2007, there are reasons. Some people don’t want to change. They know how to get what they need to get done done. Many companies figure that they have spent the money, have the product, and have no reason to change. Others don’t want to spend the time or money to re-train staff and spend money on upgrades. Neither is a small expense. There are lot of other solid reasons for not changing.
My attitude is that almost all companies should choose one of two paths. Either get on a Microsoft Office 365 program or go with LibreOffice. Either way, you will be far ahead of where you are now. The Office 365 program offers a lot of bang for the buck and is not so expensive as to be prohibitive. Office 365 is from $8.25 per user per month to $35 per user per month. I and my clients usually opt for “E3” $20 per month per user packages that cover everything I would ever need. LibreOffice is free and very powerful. LibreOffice is open source and has a very active developer base.
Do yourself, your employees, and your clients a favor, look into your options.
