If you are a Mac user , you must have used the cool Expose feature which lets you switch between multiple apps easily. Now the iPhone 4.0 OS might get Expose like Multitasking according to a report by Apple Insider
This is what the report says
The upcoming 4.0 reference release of Apple’s iPhone OS will deliver new support for running multiple concurrent third party apps, and allow users to switch between them using a windows management mechanism similar to one made popular on the company’s Mac OS X operating system.Those familiar with the design of iPhone 4.0 said that the user interface will resemble Apple’s desktop Expose feature, in that a key combination — reportedly hitting the Home button twice — will trigger an expose-like interface that brings up a series of icons representing the currently running apps, allowing users to quickly select the one they want to switch to directly. When a selection is made, the iPhone OS zooms out of the Expose task manager and transitions to that app.
With zillions of apps on the Apple App Store currently , lack of multitasking is totally disappointing . Users have to exit each app before using another one although native apps are able to multitask. Seems like Apple will bring a new style of handling multiple open applications in the upcoming version of the OS . Many users who are upset with lack of multitasking in the current version of the iPhone OS have used 3rd party apps to run apps in the background.
If you consider Multitasking on other platforms Symbian , Windows Mobile , Blackberry and even Android support running of multiple apps simultaneously. iPhone got MMS really late but was not really exciting, but official multitasking support will make iPhone users rejoice for some users tend to call the iPhone an App Phone
