For many people, it's a safe bet that the iPad will not replace or preclude the purchase of a Netbook. A quick look at the specifications and it's pretty obvious why.

The iPad is definitely not a laptop and that's not necessarily a good thing.

As this tweet succinctly put it: "What has no webcam, no multitasking, no HDMI port, and (possibly) no Flash, and costs $500? Hint: Not a netbook." This tweet, of course, is referring to the Apple iPad. And, by the way, you can eliminate the parenthetical; the iPad definitely does not support Adobe Flash video. (Also see this post at Gizmodo.)

But specifications aside, here's the most fundamental difference. The iPad is what analysts call a purpose-built device. It does certain things very well (e.g., video, Web browsing, e-reading) and other things (most notably office productivity apps) not so well or not at all.

The Netbook--though not as fast as a standard laptop and handicapped by a relatively small screen--is still a PC and is capable of doing pretty much everything a standard PC does. In other words, it's a general-purpose device.

Then there's the physical difference. Consumers who make the leap from a notebook or Netbook to a tablet will immediately recognize the ergonomic limitations of a tablet. In short, the inconvenience of not having a physical keyboard: the keyboard on a laptop also acts as a ballast--or stand--for the screen. Needless to say, that's why laptops decorate Starbucks tables and airplane trays. (Yes, Apple will sell an iPad case that serves as a stand but that does not make it a laptop.)

That said, preemptively panning the device is foolhardy. Consumers will undoubtedly find novel ways to use the iPad. And I will likely be rubbing elbows with an iPad user at Starbucks as soon as it hits stores.

How important is the ability to multitask on tablet-class devices like Apple's iPad? Important enough that the feature will likely be touted as a trump card for Intel-based smartphones such as a tablet-size phone from LG due later this year.

How do we know this? Watch the embedded CNET video below, which I took at the Consumer Electronics Show earlier this month, and find out. Toward the end of the video (the 2:55 mark), Pankaj Kedia, director of Intel's Global Ecosystems Program for Mobile Internet Devices and Smart Phones, makes it clear that multitasking--in this case using Intel's Moblin operating system--is a marquee feature for devices running on Intel's Moorestown chip technology, due sometime in the next few months.

Kedia shows three applications running but is quick to add that "you can have more apps running."

Of course, on an Apple laptop, where a user can easily have a dozen or more apps active, multitasking is taken for granted. For example, users can watch a video feed while writing an e-mail. For the iPad, however, Apple is betting that the snappy interface, as demonstrated in this CNET video, will more than compensate for the lack of multitasking.

On Friday, I asked Keida about the importance of multitasking on Intel-based smartphones and tablets.

"Consumers want to do multiple things at the same time: listen to music while browsing the Web, look for directions while looking at your calendar and talking with your friends, and so on," he said in response to an e-mail query. "Multitasking is one of the key differentiators for the LG GW990 smartphone, based on the Intel Moorestown platform," he said.

To date, Intel has gone public on three Moorestown-based designs. The LG GW990 smartphone, the Aava Mobile smartphone, and the OpenPeak tablet. "The LG GW990 is a product, while the Aava and OpenPeak are two of our leading reference designs, which will generate multiple end-user products," he said. "As we launch Moorestown in [the first half of this year] and products begin to ship in (the second half of the year), you will hear about additional customers."
