it has google hangout, though, right?

IM/VOIP software isn't like email where you just need an option, unless your only use for it is for making out-of-network calls (e.g. Skype-to-phone).

If all my friends, all my colleagues, and all my clients are on Skype, then having an alternative doesn't help at all.

Yes. But only if it would matter to current skype-users.

I think Facebook would be able to replace skype quickly (since everybody have Facebook), but not Google.

If they have a Chromebook, it's a good bet they have a Google account. Hangouts are one of the "apps" installed.

I'm getting crazy on this. Just quick recap:

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".

How is it related at all???
