1. I did a statement that people who need skype won't buy it.
2. Someone told me that "these things have hangout instead".
3. I pointed that it doesn't matter since all your contacts are still in skype (and their contacts too), so you'll have to switch them all to hangout too.
4. Now you're saying "If they have a Chromebook, it's a good bet they have a Google account".
I think Facebook would be able to replace skype quickly (since everybody have Facebook), but not Google.
