Superior to other laptops and cheaper than the cheapest iPad, this product's launch is history in the making.

NEW YORK (TheStreet) -- At the same moment that Google (:GOOG) accidentally posted its quarterly earnings release, Google also unveiled its technology broadside against Microsoft (:MSFT) and Apple (:AAPL): The $249 Chromebook laptop. This is a very significant threat to Microsoft, Apple and -- as I will describe in more detail below -- Intel (:INTC) and AMD (:AMD).

Google's Chromebook, made by Samsung, looks almost identical to an Apple MacBook Air 11.6 inch. However, while the Apple laptop starts at $999, the Google/Samsung laptop is 75% less expensive.

It may also be the first volume-manufactured laptop to not have a fan, because it runs so cool. It is therefore as quiet and cool as any smartphone or tablet. No noisy fan which draws power and blows hot air out of the laptop.

Enabling this industry-first fan-less laptop, is a Samsung chip that is among the first to be based on ARM's A15 architecture. This is basically the kind of chip that is just now starting to hit the highest-end smartphones in the market.

Google is able to run an entire laptop (and soon also other desktop PCs) based on this cell phone chip because its software is so much "lighter" (or "more efficient" if you will) than any laptops running Apple or Microsoft operating systems. This makes for Google, with Samsung's help, to sell a laptop for significantly less than the competition.

In addition, because the $249 Google laptop also runs cool, it will not feel like a hot potato in your lap, regardless of whether you are wearing shorts, jeans or whatever. Think of it as an Apple MacBook Air, but as cool in your lap as the iPad. In other words, this is the holy grail of computing, folks.

The Google/Samsung $249 laptop manages to squeeze at least 6.5 hours of battery life, while weighing only 2.5 lbs. It's only 0.8 inches thick. These specs mean that it is not only visually similar to the 11.6 MacBook Air, but that it also performs like a champ. However, for every MacBook Air you buy, you can get four Google laptops.

The Google laptop will be available to buy either from Google directly online, or from Best Buy (:BBY) and Amazon (:AMZN) -- among other places -- Steve Jobs'-style "shipping on Monday," Oct. 22.

Those of us who are Google shareholders may have suffered a temporary setback with Thursday's unfortunate Google earnings release, but Google's revolutionary new product creates a new kind of pain and inflicts it on the computing world: Microsoft, Apple and for that matter Intel and AMD, simply cannot compete at this point.

When the dust settles from Google's earnings release, next week's launch of Windows 8, Apple's new iPad, and much more, what the world will remember five or 10 years from now is the Google laptop. Microsoft and its partners sell products of questionable popularity, priced mostly from $500 to $1,000; Apple is selling laptops starting around $1,000; and Google's beautiful device with some superior specifications comes in at a price lower than even the cheapest iPad.

I have spent the last 22 months working a majority of my time on the predecessor devices to this $249 Google laptop, and I got time to work on this latest version this morning. I can say with confidence that it is the best value -- by a mile -- you can get for spending $249 on any kind of technology. You should order as many as you can, and make it the Christmas stocking present of choice, for as many people as you can afford.

If you are Microsoft or Apple -- or for that matter Intel or AMD -- you just had to go to the bathroom and feel ill. How on God's green Earth can they respond to this bombshell by Google?
