Entelligence is a column by technology strategist and author Michael Gartenberg, a man whose desire for a delicious cup of coffee and a quality New York bagel is dwarfed only by his passion for tech. In these articles, he'll explore where our industry is and where it's going -- on both micro and macro levels -- with the unique wit and insight only he can provide.

The idea of multitasking on mobile devices has been a hot topic for years. It's been debated since the early days of smartphones, when devices such as the Treo based on Palm OS could not handle more than one task at a time, while handsets based on the Windows Mobile platform had the capability. The issue reached a crescendo with the release of the iPhone (and more recently with the iPad) and lack of multitasking capability for third party apps. This week it's come up once again, with news from MIX10 that Microsoft would not support multitasking for third party apps on Windows Phone 7 Series, at least initially.

I think it's a non-issue for the most part, and that Apple and Microsoft are doing the right thing for the mass market by limiting multitask use for third party apps. The irony here is that one of the biggest criticisms for years was Windows Mobile's lack of a task manager and the ability to kill applications that were running. Complaints were so high about multitasking that almost every phone shipped with some sort of third-party task manager. Likewise, the first software I download for any Android device is a task manager to kill background tasks and apps The reason is simple. Running in the background, too many third-party apps overuse system resources, memory, and network to the point where almost any machine with multitasking capability ends up running slowly and killing battery life. With fast suspend and resume of existing app processes there's very little need for most third party apps to run as background processes, with a few notable exceptions.

It would be easy to simply dismiss third party apps running in the background, except there are two use cases that do matter. First are music apps such as Pandora and Rhapsody. I'd love both of those apps to work on the background of my device and using those apps on Android and WebOS phones is a big differentiator. Second, GPS and turn-by-turn direction programs both benefit from the ability to access GPS content while another app is running such as a navigation program. There's arguments for apps like Twitter as well but I think most of those use cases could easily be handled through things like notifications services to let me know something has happened.

What I'd really like to see is Apple and Microsoft figure out some way to allow third parties to do multitasking and run in the background. While it may not be a mass market case, there's a lot of folks like me who want to be able to control this activity. It really needs three aspects. One, the ability for me to designate which applications I want to run as background tasks. Second, an easy way (as Palm has shown in WebOS) to switch between them. Finally, there needs to be a way to kill unneeded apps -- in particular, this is where Windows Mobile 6.x and Android fail, despite their multitasking capabilities.

Multitasking is far more important on the personal computer -- whose windowed UI and raw horsepower make it not just a luxury but a necessity -- and one way the personal computer trumps the phone. That said, vendors need to address the mainstream use case of background media functions and location services for third parties to truly make their platforms valuable to users. Longer term, the smart ones will let the power users make the call of performance and battery life for themselves.

One use case I have for multi-tasking is using Messenger in the background, managing my contacts/details, getting push mail, taking notes and storing links I will use later while on the road. I also might be listening to music as well.

It's a simple example of multitasking on a smartphone and one that has been doable since... the early 2000's.

Is it harder for the normal users to figure out how to make it work? Sure since most people don't even know they can do that on their phones. However, the people who DO buy smartphones already KNOW they can do this and generally are running multiple programs at the same time.

We're not talking about running multiple, complex, process heavy programs. Just simple, day to day programs that bring convenience such as notes, IM, musicpossibly some streaming every now and then.

Can these be done with some of the newer platforms? Sure, in a more limited manner and I think that is all fine and good for the majority of people who are generally new to the smartphones.

But for smartphone users, as in people who buy smartphones because they can do certain things with it, they already know and do need this level of functionality. We can't make the mistake of allowing the general populace decide if an important function like that is or is not going to be important for people. The smart thing to do is to create devices for the masses and devices for "power users" or users who actually use their phones rather than getting it for the cool factor.

It certainly isn't a myth. The myth is making the mistake of assuming multi-tasking isn't necessary because the general users have no idea what the hell it is. That's why different categories of devices exist or has the introduction of the iphone suddenly made the media completely ignorant of this?
