i am thinking of replacing my vista with ubuntu.
Questions:
1) what will be the advantages and disadvantages of using ubuntu instead of vista?
2) what will be the setbacks of replacing my vista?
3) how hard is it to cope up with the new OS? what must i learn to utilize ubuntu?
You can run both for a while with dual boot, and judge for yourself. Vista costs more, probably loads the system more, Ubuntu/LINUX X Windowing is a bit different GUI, and a lot depends on what you do with the Vista now. If you just do email and browsing, not a problem, I groped through them. For word processing, spreadsheets, etc., I have not used Ubuntu for that. For programming, like JAVA, not a big difference.
