Is the XPS 13 2-in-1 7390 not available to order in your country yet? Well, despite claiming that it was aiming for a simultaneous worldwide release, yesterday's launch only applied to the US. While Dell has publicly left other markets in the dark about a wider release, Dell Customer Support has been more specific. Unfortunately, it looks like everyone outside China and the US must wait a while longer before getting their hands on an XPS 13 2-in-1 7390.
