evolution for mails and calendar, linux compliance

[usuario_habitual]

Hi!!
I think that the good direction of this project and computing in general, is adding free software that we can found both in windows and linux, so we will be able to save our files in a pen drive and to go to other machine with the same free software running on a linux machine. So a good idea would be incorporate for example evolution as mail client and calendar, and open office as ofimatic suite. I know maybe it would become in a too large file installer. What do you think?
