Toshiba unveils new high-end ultrabook
Toshiba has pulled the wraps off a new series of notebook computer called the KIRAbook. The machine is an all-new ultrabook promising a lightweight and compact design thanks to its magnesium alloy chassis.

Toshiba promises that the screen delivers razor-sharp clarity for text, photos, movies, games, and other content types. The KIRAbook will be available in standard, and touch screen versions -- the touch screen version of the ultrabook supports 10-points of touch and Windows 8 gestures.
Toshiba says that a high-capacity lithium polymer battery promising all-day battery life, while storage duties are handled by a 256 GB SSD. The ultrabook will offer 8 GB of 1600 MHz memory and a range of third generation Intel Core processors.
Pre-orders for the KIRAbook will kick off on May 3 with purchases starting May 12 online. Pricing begins at $1599 and goes up to $1999 depending on the processor chosen.
The KIRAbook joins other high-resolution 13” notebooks like the

Higher pixel density matters more the closer a display is to your eyes. It is all about viewing distance.
This is why you can get away with about 35PPI on a 60" HDTV that you view from 8' away while you need closer to 100PPI with a 23" LCD to get approximately the same sharpness.
With computer displays you're viewing them at about 2'-3', about a foot and a half with laptop display, about a foot with a tablet, and finally about 10" with a smartphone.
Needing greater pixel density with greater display sizes does not follow given that viewing distance increases accordingly. It is the opposite, the larger the screen, the farther the viewing distance, and the lower pixel density is required.
It makes sense given that you are able to discern individual larger pixels and screen door effects the closer you are to a display. This is why going over 300 PPI was so important with smartphones, while doing the same with a desktop display goes well past the point of diminishing returns.

You're varying the screen area very disproportionately with the distance from your eyes.
My eyeballs are right about two fee from my 24" desktop monitor. When I set my 17.3" laptop on my lap, my eyeballs actually wind up being closer to 26" away from that screen...and trying my best to juggle my cell phone and a tape measure at the same time, it seems I generally hold that around 16" from my eyes.
So my phone, with it's 3.7" screen at 800x480 is about a third closer to my eyes than my 24" monitor at 1920x1080. Meanwhile, the decrease in display area is roughly a factor of 42. The screen area of my cell phone is a smidge over 6 square inches, vs. 252 inches for my monitor. It's literally 42 times smaller.
That 1/3 change in distance pales in comparison to the change in surface area. While obviously viewing distance is important, the size of the screen you're talking about isn't less important - looks like it's more important to me.
Subjectively speaking, I can look at a photo on my cell phone, and then on my desktop monitor, and honestly say the quality appears to be the same. It really makes no difference - even though my cell phone has such a "pathetic" resolution by your "standards."
So no...massive PPI on a cell phone actually *is not* important. It just isn't.

So you're saying that you use a small laptop even farther away than a desktop monitor? Do you gorilla arm the keyboard?
Your logic is backwards, and as usual you use it to justify something inferior. Just because you don't care if something is objectively inferior doesn't mean that everyone else shares your incredibly low standards.
I mean, if you like a Kia, great, but don't pretend they're better than a car that costs twice as much simply because its cheaper.
