can't one just install a different OS? or is the chromebook pixel using some weird hardware?

Chromebook used to be locked down iirc. Anyway it isn't anymore, so yes you can install *nix or whatever on it.

Chromebooks never used to be locked down.

Let's continue this digression. Fun fact I learned recently about guided missiles (I have diverse interests), modern ones don't adjust to aim directly at the target, they adjust to keep the target at the same relative angle (the same position on the imager). This has the effect of leading the target and flying an intercept course instead of a following course, which is more efficient and effective.

Umm, "modern ones"? Meaning practically the first one, Sidewinder: http://en.wikipedia.org/wiki/AIM-9_Sidewinder#History "The Sidewinder also included a dramatically improved guidance algorithm. The Enzian attempted to fly directly at its target, feeding the direction of the telescope into the control system as it if were a joystick. This meant the missile always flew directly at its target, and under most conditions…

By "modern" I mean a subset of systems which excludes first generation systems as well as some second and other generation systems, it's generally just simpler to say "modern" than be more specific. If I said "modern computers use integrated circuits" the timeline of modernity would be clear, I don't mean state of the art, just not archaic.

This video of the Sprint ABM missile (0 to Mach 10 in 5 seconds!) shows it intercepting a ICBM RV in a test - given the speed of the RV it does look like the missile is aiming where the RV is going to be rather than where it is - and this is from the 1970s: http://www.youtube.com/watch?v=msXtgTVMcuA

Another fun fact, the Sprint's first stage only fired for 1.2 seconds.

Do we really need retina displays? Or are they just trying to make something new for us to spend money on? Right now Sony ASUS and Lenovo are doing fine. Nice headline. You got me to read the first paragraph or so.

I'd say we don't "need" retina displays (much like we don't need unibody laptop shells).

However, it's really nice to have them as a luxury "standard". It's been too long that computer displays have been held back by 720p/1080p inertia.

Shockingly short-sighted post. Apple does not make it's profits from feeds & speeds (e.g. Retina display). It makes its profits, and delights its customers through its vertical integration; its excellence at every point of the customer experience from design, to supply chain management, to manufacturing, to distribution, to marketing, to advertising, to retail, to sales, to post-sales, to support, to software, to ser…

Except that in this particular case: - Google is vertically integerated, at least to as high a degree as Apple is with Macs - Google is trying to sell a physical product at high margins - Google is heavily rumored to be setting up its own retail presence Honestly, you'd think that at least when we're discussing a $1300 laptop, the lame "you're the product" cliche could be avoided.

"Honestly, you'd think that at least when we're discussing a $1300 laptop, the lame "you're the product" cliche could be avoided."

You'd think so but especially not here, everything you do will be "seen" by Google. So, you'll be paying $1300+ for a browser and be tracked massively by Google to "serve you better ads." Yay!

>Sony, Asus, and Lenovo all have notebooks at similar prices, but none have a high density display and none have only solid state storage. Huh what? A lot of ultrabooks have only SSDs, has the author been in coma for the last year? Sony has a Vaio Duo 11" with a 1080p display. Lenovo and Asus also have or are about to have high density displays. All in all, an empty uninsightful fluff piece. Also, please get some con…

I just purchased an Asus UX51VZ with 2x128gb SSDs and a 15" 1080p display that weighs less than a Macbook Pro Retina, for $400 less than the Macbook would've cost. The Retina has a couple of big wins over the UX51VZ (battery life and higher resolution display) but I wouldn't put them in different classes, or claim that Asus isn't even trying.

The word you're looking for is "mature."

Maturity of a technological system to me implies a plateau of design, but that's not the case in missile guidance. Current generation systems are significantly more advanced and more capable than previous generation systems.

Yes, sorry for nitpicking but I just think that the word choice was perhaps not good. I'd think modern missiles means something much more recent easily, when this is talking about something practically existent for the whole development time of missiles. Sidewinder development was started in 1946.
