If the Toshiba Satellite Radius P55W-C looks and sounds familiar, it should: It's an upgrade of the Toshiba Satellite Radius P55W-B that I reviewed almost exactly one year ago.
Aside from cosmetic changes (a dark gray color scheme in lieu of lighter/silvery tones), a significant upgrade to the LCD (more on this later), and Windows 10, it's the same Satellite P-Series you know and love. Well, tolerate without too many complaints, anyway.
The big selling point remains its two-in-one status. With a full 10-point touchscreen and 360-degree hinge, you can use the P55W as a laptop, a slate, or in tent mode for media viewing. The big, 15.6-inch screen makes it a better portable TV than most, and the addition of a numeric keypad gives you more room to stretch out for hardcore spreadsheeting.
The big switch is the screen, which now boasts 4K resolution of 3840 x 2160 pixels. Windows 10 is a little better prepared for this level of detail than Windows 8 (and earlier), which means you won't suffer quite as much through ultra-tiny dialogue boxes if you use it at full resolution. That said, unless you're watching 4K content (which you're not) it's easier to get around if you knock the resolution down a few ticks. The sacrifice of losing some windowing real estate is worth the added usability.
Windows 10 is the other big change, though since the upgrade is free it's not really much of a sell. However, there's some comfort in knowing all of the machine's components will actually work with Win10, said the guy whose new laptop lost its webcam to a Windows 10 driver issue. Some minor component upgrades—a fifth generation Core i7 processor, a bump up to 12GB of RAM, and switching from a 1TB disk drive to a 512GB SSD provide some punch in the benchmark department. All told, the P55W-C tested at about 30 percent faster than the P55W-B. (Though you still shouldn't expect to use it for serious gaming, particularly at full resolution.)
