Excerpt: Though you wouldn’t know it from the name, the P55t is not like the hoards of Satellites already made by Toshiba. Why? Because it has a 4K display. The proliferation of 1080p has raised the bar on quality, but the P55t easily hurtles it into the stratosphere. Pixels are virtually indistinguishable at any reasonable viewing distance, the backlight is bright, and colors are rendered with a vibrancy few laptops can match.
Pros: 4K display, Powerful hardware, Lots of connectivity and a Blu-Ray drive
Cons: Short battery life, Heavy and thick, Price is an open question
Conclusion: Still, outside of some niches such as gaming laptops (which the Satellite is definitely not), it's hard to get too enthusiastic about a Windows 8 system without a Windows 8-optimized touch interface, at least at $649. The P55-A5200 would be more tempting at $500 to $550—and as more touch-enabled laptops are released this fall (some with Intel's battery-saving fourth-generation "Haswell" processors), that price point may be coming soon.
Pros: Polished, professional design and build, Backlit keyboard, Admirable array of ports, Crank-worthy Harman Kardon speakers
Cons: No touch display, Battery lasts less than four hours, DVD tray positioned for accidental pop-outs, 5.2 pounds feels heavy versus ultrabooks
