Use an Open Source Software with some PIM and office applications.
eyeOS is an Open Source Web Desktop Environment, commonly known as Web Operating System (Web OS) or Web Office. eyeOS is Open Source Software. The basic System comes with some office and PIM applications, and the complete eyeOS software database can be found at eyeApps and in the public server.
What i love about this product is that it has allot of potential. There are still tons of bugs to work out but the interface is great and the concept is there. The best part is that its free and all the tools that it comes with are use full in a business environment.
Cons
The oly drawbacks are that its not quite ready to be used for big businesses and for people really looking for an office platform. The reason being it cant beat the abilities of the regular desktop yet. It really needs the web version of open office. Its version of Word and Excel don't really do anything. All they give you is a basic WYSIWYG editor. Way to standard. And for all of you people that use the features of Excel will despise their because all you can do is type is cells. The advanced functionality is non existent.
