Both OpenOffice.org and Google Docs contain a word processor,
spreadsheet and presentation program. OpenOffice.org adds to the trio a
drawing program and database, while Google offer email (with contacts),
a calendar, and a host of other services. A fantastic selection of
software, but certainly not everything you need to run an office.
On the OpenOffice.org mailing lists, we are often asked, “Where is
your Outlook?” Those users have normally identified the equivalents to
Microsoft Word, Excel, Powerpoint and Access, but wonder how they are
going to handle their email, contacts and calendar. They often express
their desire to “get completely free from Microsoft”, and are concerned
they may need to continue using Outlook. They are looking for a
replacement office suite from a single replacement company.
But open-source projects (with the exception of Koffice) rarely try
to do that. They prefer to do one thing well, and allow others to focus
on what they don’t do. This is in stark contrast with Microsoft, who
prefer that every piece of software you use has their logo on it.
