Although he didn’t state it outright, there was a hint during his address of something more. What, it seems to me, Benioff hinted at was that Visualforce combined with all the other platform components beneath it could in fact rival Microsoft Windows, at least as a quasi-operating system.This occurred when Benioff ticked off the many different types of devices that developers could design a user interface for using Visualforce. Among those devices were laptops, desktops, mobile devices and even medical devices. If, Salesforce is indeed targeting medical and other industrial devices that typically use an embedded proprietary operating system or one with somewhat limited capabilities like Win CE or an OS from Wind River, then Visualforce could become the front end for an online operating system that includes the security, the database, the application layers and now the UI.In an interview following the keynote, Parker Harris, a Salesforce.com co-founder said the technology for working off line, which includes the UI, is currently part of the platform. At first blush an on demand embedded operating system sounds like an oxymoron. However, add in more reliable networks, the ability to work off line when needed, and the ubiquity of online access through Wi-Fi and cellular, and it begins to sound far less outlandish. By starting with devices that have limited capabilities Salesforce could be heralding a major advancement in what the future network is able to deliver. Technology Industry
