Apple up for some great changes in the iPhone OS 4.0 that powers iPad

After a lot of hype about the document that leaked from HP regarding the Slate comparison with the iPad, net surfers and many potential iPad or Slate customers know it quite well the upside and the downside of the Slate and the areas where iPad is due to face tough competition from the Slate.

But Apple is offering a sneak preview of its forthcoming revision of the iPhone operating system that powers the iPad. Does that mean we are in for some great changes that might get revealed in the Thursday press release on the iPhone OS 4.0?

Undeniably the HP Slate is going to give a killing competition to the gadget king Apple’s most talked about iPad. To sum up, what Slate argues as its pluses against the iPad are, first and foremost it runs on Windows 7 Home Premium whereas the iPad runs on the iPhone operating system. So what is the downside of it?

Apple’s iPad does not run the Macintosh or Windows OS therefore it can not run programs designed for them. It runs on iPhone OS which is compatible only with iPad and iPhone apps. This enables you to remotely control Mac and Widows computers. So in a way the iPad lets you indirectly run Windows or Mac programs through its screen but that does not imply that you can run them locally.

Another strong argument posed by the Slate from HP is the multi tasking feature that iPad definitely lacks which means that you can not run more than one program at a time in your iPad. But iPad limits multi tasking to some of its built-in apps.

It means that for example if you are in the middle of downloading music, you can not check your e mails without closing the download. As you do that the music stops as you shift to other apps. Another threat the Slate poses to the iPad is 2 cameras, one VGA at the front that enables video conferencing and another 3 MP camera at the back.

Apple’s iPad also lacks a USB port but it comes with a connector port similar to the one in the iPod Touch and iPhone. It comes with a cable that connects this port to a USB port on a Mac or PC. This lets you sync your music, photos, apps, videos and many more to the device. But among all that hue and cry about what Slate boasts of having over the iPad, there are possible threats from the iPad in the areas of battery life and the price tag.

Slate offers a battery life of 5 hours, which is just half of what is offered by Apple’s iPad and the price tag of 16 GB version which is $499 for iPad as against $549 for Slate.
