just changed few pc to Ubuntu, no more MS...
There are quite a few issues in beginning, constant download of softs for adapting system to watch video, to find a PDF converter,to get a toolbar,...there are issues with all the open softs, such as thunderbird and mozilla, as we made a full open source jump... but all in all Ubuntu makes it quite easy with the add or delete soft...
the main problem i have actually using Open softs, there i mean Open Office, is with excell sheets !
print something and something else comes out, another spreadsheet,not the one on screen, Save a file and some numbers return to old numbers...Well it is annouced that you should save in open office format, as excell format migth not be able doing all formulas... Should be a way around this, but for the mo it is double check all files before print or send...
