Salespeople are the most avid users of business apps, and I think the “Holy Trinity” of business apps would be for Word Processing, Spreadsheets, and Presentations. I might just as well say, Microsoft Word, Microsoft Excel, and Microsoft PowerPoint. Microsoft still dominates the market for Windows-based business applications software. It wasn’t always like that though. I’ve written about Microsoft stifling innovation in a previous article, and I was reminded about how widespread this has been when I did some research on cameras in phones.
