AAPL) iPhone 5 by $300, or almost50%. 7-inch Tablet: The $199 Nexus 7 undercuts the $329 iPad Mini. 10-inch Tablet: The $399 Nexus 10 undercuts the $499 iPad 4. Laptop: Already the price leader with the $249 laptop, Google's newlaptop -- made by Acer -- at $199 undercuts most new Microsoft ( MSFT) Windows 8and Apple laptops by 60% to 80% or more. It wasn't even a full month ago when Google caused jaws to drop whenit announced the $249 laptop made by Samsung. I wrote about it in Google Drops the Neutron Bomb: $249 Laptop and $249 Google Laptop vs. $499+ Windows 8: Fight!. The new $199 Google/Acer Chromebook laptop has an Intel ( INTC) Celeronprocessor, for which Samsung charges $449 in their Intel-basedChromebook. It's also got a 320 gig hard drive, which seems totallypointless in a computing architecture where only the little stuff youneed right now can fit within a few gigs or even less. You can stillget 100 gig of storage in the cloud, which Chrome OS makes availableto you as you need it. I have yet to actually test this Acer, which was announced only hoursago. I hope to start testing it within the next couple of days. Itdoes seem as if the boot time (18 seconds) will exceed that of otherChromebooks who run 8 to 10 seconds for the same task. Who might prefer this $199 Google laptop over the much more expensive$249 version? (That was a slight joke, by the way.) The answer isprobably found in either of these three categories: 1. Those for whom the Intel processor will be faster than the SamsungARM version. 2. Those who have unusual local storage requirements, such as extremephoto needs or very large loads of huge documents needed locally. Theemphasis here is on extreme. 3. Price, price, price: $50 may be what some tip a barista in aweek; for others it's a minor fortune. With the material caveat of not having laid my paws on this new $199Google laptop yet, I can imagine there are still numerous realand potential advantages of the $249 Samsung version over the $199Acer. Here are the top four:
1. Weight: The Samsung is 2.5 lbs compared to Acer's 3.0 lbs. 2. Battery life: The Samsung is 6.5 hours compared to Acer's 3.5 hours. 3. SSD reliability: The Samsung won't suffer a hard drive breakdown. 4. Heat and fans: The Samsung doesn't have any. Who would buy the $199 Google laptop over the $249 version? They maybe schools, storage freaks, or those who do computing-intensive tasks,perhaps gamers. It's somewhat unclear until I have had a chance toactually use the Acer. Here is the larger point, though: At $199 or even $249, Google mayhave granted the world an entry ticket into "disposable computing."For Christmas this year, why not buy half a dozen? It's only $1,200or $1,500 depending on the version. One for each child and relative. Other use cases: Put a Chromebook in every room, at home as well asat your office. They are inherently multi-user in architecture, soyou never have to be afraid that someone else will mess with yoursettings, access your documents or email, or attract a virus. You arecompletely sandboxed from your kids, other family members, visitors,colleagues and other guests. Painless and safe. In the old paradigm, you would take your laptop from work to home,then back to work again. Unless you have to stop and use it somewherealong the way, the Chromebook allows you to forget about thistransport. A Chromebook is essentially the same experience whetheryou own it or not. Your documents are most likely always accessiblefrom any Chromebook you happen to have in front of you. Users of Microsoft and Apple PCs sometimes laugh at Chromebooks.Often, I think that nervous laugh is mostly because they can't admitthat they just spent anywhere from $500 to $2,500 on a laptop thatwill require many trips back to the store, back to the antivirusprogram and back to the update button. And we didn't want to get rid of those trips, did we? Well, Google did. At the time of publication, the author was long GOOG, AAPL and MSFT.
