www.lpakenya.org - recently launched Linux Professionals Association
www.osskenya.org - just recently come across it.
I wonder how many people and organisations in Kenya actually use a Linux distribution for ordinary day to day tasks.
I use Ubuntu for my personal (and non day job :) ) stuff but unfortunately :( have to use Windows at work - policies). OpenOffice for Documents, AmaroK for Music, Firefox for the web, I'm about to start on GnuCASH for my personal finances, GAIM for Yahoo,MSN,gtalk, skype for linux(no video though). List is long.
There's lots of legal FOSS software alternatives available - have a look at this chart:
and this website: http://www.osalt.com/
I think for a developing country like ours, more and more people and organisations need to be exposed to FOSS alternatives which will go a long way in reducing the cost of software ownership (legally that is :) ), while, due to the very nature of FOSS, encouraging development of custom/homemade software solutions and services.
