Our several experiments represent a significative development effort which should be seen as an investment for the future. The desktops will probably become less used than today. Especially in the outreach domain, we will have great opportunities to develop mobile applications and services. The Virtual Observatory offers a way to access a large amount of data through standardized protocols and added-value services developed on top of these data (e.g. efficient cross-match services). All these data sources and all these services will be easily reached from everywhere through the mobile devices. The mobile applications can be seen as light interfaces able to access to a large variety of data and services. The future of the Virtual Observatory is probably in the pocket!
