Evolution:
-Mainframes as the computing platform (IBM)
--- PCs as the computing platform (Apple)
------- the OS as the computing platform (MS Windows) (Where Apple missed the boat by only offering their OS on proprietary hardware)
------------- the Internet as the computing platform (Google) (where MS will probably miss the boat)
every time I fire-up and use OpenOffice, I hear the 'cry' of another microsofty programmers` heart, breaking in two ... guess I fall in the second half.
1. It's free
2. It can read all Microsoft and open formats
3. It can export as PDF
4. It runs on Windows, Mac, Linux, ... (written in Java I believe)
5. It's open source
6. Various other features have been added which MS now adds to MS Office in order to catch up (like auto-completion).
Last time I checked, none of the online web two point ooh software can open big documents. These web-apps only match probably 20% of MS Office features and it's simply not enough these days when people are more tech-savvy than in the past.
