having impacts on sells of netbooks does not mean that should be counted in PC sells. There are tons of other markets that are effects by different once but items in them are still considered different.
Should we count TV as computer monitor sells because yes it steals from computer monitors because people will be a TV and use it as a computer monitor big time at 1080p ones?
No we should not. Still very different markets. But they do effect each other directly.
While I have heard of certain 1080p televisions advertised as 'computer ready', I certainly haven't heard of them having any effect whatsoever on computer display sales. Have you got evidence?
Smart phone easily could be stealing from netbooks sells, iPod Touch could easily be shown to be stealing sells.
Should they be counted?
No they should not.
Why not? If they've been having an effect on netbook sales, then they should be counted. However, neither the iPhone nor any Android devices had any visible effect on netbook numbers, but the iPad most definitely generated a visible effect that has pushed two brands that leapt up the listings with their netbooks back downward again. Even laptop computer sales visibly dropped after the iPad was introduced -- by every brand except Apple. With the possible exception of Toshiba, Apple was the only brand to see double-digit growth in computer sales,
not counting iPads, while many major brands saw single- or double-digit losses last year.
I would even say other tablets running android should not get counted.
Lines are blurred but there comes a point were it is clear they crossed it. This one people screaming iPad counted as PC just seems to be covered with Apple Fanboys screaming how great it is.
And why not? Android is nothing but a different version of Linux, which is even considered a computer OS while nearly everybody denigrates iOS as only a smart phone OS -- totally ignoring the fact that it, too, is a version of OS X which is a fully-certified stand-alone iteration of UNIX.
Is the iPad a computer yes it is, so is the iPhone and iPod touches are computers. But is it a PC hell no. You do not want it to happen because it complete wrecks you case. 240% increase in sells at the size of Apple is pretty much BS. Only people who get caught up in this are either Apple fanboys or people who do not understand the market. You also have failed to address the issue that Steve Job the Apple fanboy god has even said that the iPAD IS NOT A PC
Now, you, yourself just acknowledged that the iPad is a computer, no? PC stands for Personal Computer, no? So, the iPad is a Personal Computer, though I will acknowledge that it doesn't have the same kind of power -- yet -- that a full-blown desktop or laptop computer enjoys.
However, just as the netbook was intended to be an in-between, mobility device for the technical crowd, the market for them exploded because it offered cheap computing for the consumer -- a market it was never intended to meet, though the concept originated as an inexpensive way to bring computing to the people of third-world countries who flat couldn't afford to buy even basic desktop computers. Steve Jobs and Apple saw this new market and realized right up front that the netbook was a stop-gap device, not truly a mobility device as such; it simply had too many limitations.
It is well-known that Steve Jobs doesn't like to go off half-cocked (shooting reference) and release a half-made product. The results of experimentation triggered the launch of the iPhone and iPod Touch as a kind of new-style PDA, just after the regular PDA market effectively died. It took no time at all to realize that he had a hit on his hands and started looking at ways to improve on that base. If you look at it, the 1st-gen iPad is roughly equivalent in capability to the iPhone 3G(s), though it also offers things the iPhone itself doesn't include even though it has the memory capacity to perhaps do them.
So yes, in many ways the iPad is "just a bigger iPhone without the calling capability". Well, Skype gives it the calling ability. However, the iPad, as I said, has other abilities that come closer to the abilities of a netbook than even the iPhone does; the screen is large enough to create documents and makes photo editing and other tasks easier than even the tiny screens of the early netbooks (which were only 7" diagonal if that much). Newer netbooks have grown to larger screens, but many of those are now called sub-notebooks due to increased size and performance than they are 'netbooks'. The touch interface makes doing these tasks even easier than doing them on a full-powered notebook -- excepting text-heavy editing, that is.
Where's the delineation between smart phone and computer? Apparently screen size. If you'll note, Motorola has prototyped a docking station where a smart phone can be plugged in and have a full keyboard and large display available. That should easily let it fit into the netbook category, no? Other companies have already built cases for the iPad that include a battery-powered Bluetooth keyboard that gives it even the same form factor as a netbook while retaining the touch-screen capability rather than forcing you to use a mouse or touchpad.
No, the biggest complaint here isn't whether or not an iPad is a PC, the biggest complaint is that the iPad is an Apple product that fills the same purposes as a netbook without the same form-factor; something easily added with a third-party case.
