He has once again revolutionize the tablet PC. As you know, the tabled PC has been quite a failure for many companies. Not for Apple though. It sold more than 300,000 iPads on the first day of launch and is expected to touch half a million within the weekend.

On the 8th April 2010, Steve Jobs gave a big presentation on what’s coming in the next version of the iPhone operating system.

He said there will be 1,500 new APIs for developers. Of that, he highlighted 7 big new features that most of us iPhone users will be eagerly looking forward to in the new(yet to be released) iPhone OS 4 :-

1.  Multitasking

This is the biggest news of the day from a user’s perspective. Apple is adding multitasking to the iPhone. With Apple’s multitasking, you’ll hit your home button twice. A tray will pop up with the apps you have running in the background.

It is 100% true multitasking though, rather an advanced form of app switching. Apple wants to preserve battery life, while still allowing some background processing. So, the specific functions listed below can run in the background:

• Background audio for an app like Pandora.
• VoIP so you can get Skype calls at any time.
• Push notifications
• Local notifications
• Task completion
• Fast app switching

2.  Folders to organize apps

Apple is adding a way to organize all apps into folders. With your current OS, you can probably store up to only about 9 pages of apps on your iPhone. With the new iPhone OS 4.0, you will be able to store over 2,000 apps on your iPhone. You can make a new folder, label it, then throw apps into it. Click on it, and you can see all the apps in there. So, in future, you will not need to delete apps if you wanted to add more apps.  :-)

3.  A unified inbox

With the iPhone OS4.0, you can get all the inbox in one place. In addition to that, you will also be able to have multiple exchange accounts.

4.  iBooks

Apple is confirmed bringing its iBooks application to the iPhone. Previously, it was for iPads only. Well, for a smart person like Steve, why would he want to limit his sales of the iBooks to iPad users only? If he enable it for the iPhone users as well, he will be able to multiply his earnings. i foresee this is going to be a big revenue earner for Apple in the future. With ebooks priced much cheaper than the hardcopy editions, and the ease of reading an ebook using the iPad or iPhone, this new app should do well.

5.  Enterprise enhancements

Apple’s fifth big announcement for the day was more for enterprise. Apple would like to see more Enterprise users for this neat device and give BlackBerry a run for their money. The below features will be added to enhance the Enterprise iPhone offering:-

(a) Even better data protection

(b) Mobile Device Management

(c) Wireless app distribution

(d) Multiple exchange accounts

(e) Exchange Server 2010

(f) SSL VPN support

6.  Social network for gaming

One of the key reasons why many people loves the iPhone and iPad is because of their super solid apps especially their gaming experience. To make the experience even better, Apple is adding a social network for gaming called the Game Center. In a press release, Apple says it will allow “developers to create apps with the ability to invite friends to play a game, start a multiplayer game through matchmaking and track achievements and compare high scores on a leader board.” This is gonna be a good addition for the gamers out there.

7.  iAd

Mobile ads suck says Steve Jobs, so he’s introducing the iAd. With the iAd, Apple is hoping to help developers that give away apps for free make some money. Developers get 60% of the ad sales revenue, Apple gets the rest. During his presentation Steve Jobs took a swipe at Google saying the search doesn’t work on mobile like it does on desktop. Apple wants iAds to be more interactive, and keep people in the applications. This is a genius enhancement(not so much for the users of iPhones, though) for Apple to make more money from advertisements as well as to encourage more developers to develop free Apps that could benefit the iPhone community. This is what a win-win-win is all about. Win for the developer who develops free apps. Win for iPhone users who will see more free apps offered because of the first win to the developer. And a big win for Apple who shares in the ad revenues as well as more devices sold.
