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.
The 2.6-lb machine has a 13-inch PixelPure display with a resolution of 2560 x 1440 (221 pixels per inch). 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
13” Retina MacBook Pro
13” Google Chromebook Pixel

You're completely missing the point. Upgrading a display with super high res graphics is a serious drain on battery life. A much higher pixel density requires a significantly more powerful backlight to provide the same brightness, which costs more battery power. On top of that, graphics processing workloads are significantly increased, and require more power and can provide less actual workload for the end user.
The net result is crisper text and a huge drop in battery life and a slower machine. Very few people find this to be an acceptable tradeoff.
Upgrading from a 1080p to 1440p display on a 13" device could easily cost you hours off your battery life.

The 13" Macbook Pro without retina display has 7 hours of battery life using web over wifi. The 13" Macbook Pro with retina display has... 7 hours of battery life using web over wifi.
The one with the retina display has a slightly larger battery but it is also thinner and weighs under a pound more than the non-retina version. Battery life is an engineering issue that has already been solved, and I'm assuming that Toshiba has done something similar. If they didn't go with a bigger battery, which is possible due to its lower weight, then battery life may be a problem. We'll see when reviews come out.
As for graphics, the Ivy Bridge IGP is enough to drive a 2560x1600 desktop smoothly with no stutter. The upcoming Haswell has about double the graphics performance, making performance even less of an issue.

Web browsing isn't exactly a great metric at determining how well the battery plays with resolution. Play some games, do some rendering work. Web browsing with wifi on? You might as well leave it idle. You're probably queuing almost no work to the GPU, and the extra battery power is just going to the backlight.
I also never stated the GPU would struggle by any means. Ivy bridge is more than powerful enough to power a 1440p display. But larger display = larger workloads = less idle time = less battery life.
