Computing is attending SAP's Sapphire conference to meet and talk to the software giant's customers. We are, as always, far more interested in the real-life business experience of IT leaders - our readers - than the detail of the technology itself.

But for once, I found myself genuinely impressed by a product demonstration today.

SAP has worked with BlackBerry maker Research in Motion to integrate its business applications with the BlackBerry user interface and have created a truly seamless connection between the two.

The demo featured the RIM executive who was presenting going into his BlackBerry calendar, finding a meeting with a customer, then at the click of a button bringing up that customer's history from RIM's corporate SAP software.

It is the first time I have seen a real business-focused innovation in the mobile technology world for some time, and an example of the way that business executives will be using their mobile computers - be they BlackBerrys, phones or smartphones - to really keep up with the organisation away from the office.

Email and calendars are the easy and obvious tools for flexible working, but there has been much less progress made by IT vendors in making the mobile properly a part of the core business applications that actually run the company.

SAP and BlackBerry are onto a winning combination - and an example of what will one day be the norm for business.
