If you'd rather skip the Surface Pro 9 and go for the older models, then there are some notable differences that could sway your choice and many of them are not immediately obvious when looking at the designs or even the specifications. Now that the Surface Pro 7 is a few years old, you may find stock harder to find, however.Īfter all, while the Surface Pro 7 is certainly the older device, it may still have many of the features that you were looking for, negating the need to opt for a newer, potentially more expensive model.

In fact, if you believe Bathiche, other laptop displays may never go beyond where they are now-unless they’re just interested in marketing empty numbers.With that launch, it means the Surface Pro 8 has seen price cuts, and the Surface Pro 7 can be found for even less. That’s helped guide the evolution of displays on laptops and smartphones in the years since. That, according to Apple, produced an image that was essentially indistinguishable from a printed image like a magazine, with pixels that were unable to be individually seen. Steve Jobs famously introduced the iPhone 4 and its “ Retina Display,” a display that, when held about a foot from the eye, yielded 300 ppi, “the limit of the human retina to differentiate the pixels,” Jobs said. To be fair, Microsoft certainly isn’t the first to introduce the concept of an eye limit. In this case, the eye limit is about the pixel density of the Surface Pro 7 (or Surface Book 3)-specifically 260 pixels per inch (ppi) to 280 PPI.įor reference, the Surface Pro 7 has a 12.3-inch PixelSense display (2736×1824, or 267 ppi) while the 13.5-inch Surface Book 3’s display is 3000×2000 (267 ppi) and the 15-inch Surface Book 3 includes a 3240×2160 (260 ppi) display.

That’s a function of the visual acuity of an ordinary eye with 20-20 vision, Bathiche said, at some arbitrary distance-in this case, at about a foot from the display.

On Microsoft’s displays, that’s called the “eye limit”-the maximum number of pixels per inch that the eye can see, and no more.
