There are many reasons why it would be nice to run apps not maded for linux on n900. E-swrod i such a program. I have used Katana and it is a realy good program but e-sword has an edge when it comes to have study material gatherd in one apps. And sewcondly for those who have used an app earlier there are working material yuo have that you can not move to other apps easly.
So as always inthe best of world we wold have had one OS for all computer related machines and one good app for each thing we do. Now we have NOT! so we are stucked to try to fit many things together.
