Samsung's Fold folderphone launched this week.

What do we think of it?

Three key points:

1. Samsung Fold is the world’s most important smartphone launch since Apple iPhone in 2007.

2. Samsung’s Fold is a very good first-generation device. The Fold is relatively expensive, bulky and heavy, but the foldable industry has to start somewhere, and this is a pretty good beginning.

3. Samsung Fold is expensive, at $2k retail. But keep this in mind -- foldable smartphones are a luxury gadget. Think of foldable smartphones as a Rolex watch or Ferrari supercar, a show-off product for status-seekers with deep pockets.
