But for the rest who are looking to switch over, most of them end up going back to what they were using before..not because of the know-how, but because they would have to 'tinker' with it, and this leaves a bad taste for them..

It has to be something that 'just works' and easy to use, if they are gonna spend half a day tinkering with the OS, they will soon realize it's better to look elsewhere or go back to what use to just work for them..

So to recommend someone to switch over, the OS has to:

1. Just works
2. Easy to use
3. Extendable

If you have 1 and 2, you have a loyal customer :>

For 3, this they can opt in later when they have built the confidence to do so..

So it is not trivial to recommend someone to switch over.
