Samsung ATIV Book 9 Pro is another testimony on why 4K is mostly useless on a laptop

We don’t need latops with 4K UHD screens. At least not yet. The benefits are minimal for most users, because you’ll end using scaled resolutions. That happens on Retina MacBooks since their launch, and for example the 15-inch Retina models have 2800×1800 native resolution, but you end using 1680×1050 or 1280×800 scaled resolutions.

With a UHD screen (3840×2160) you’ll end using 1920×1080 as the scaled resolution -unless you’ve got a really incredible eyesight. You’ll see beautiful detail and definition there, but the impact on battery is clear. The Toshiba Satellite P50T lasted 2 hours and 40 minutes on PCMark 8 Battery Life benchmark -3.5 hours on the Toshiba Radius 12 4K tested by Mossberg-, and although Samsung says this model lasts 6.5 hours, we’ll what’s the real number here. There’s an impact on performance too, although that is well managed by the GeForce GTX 950M included in the package.

The $1,599 price tag isn’t that bad for what Samsung offers in terms of specs, but if you value battery life, 4K laptops are not the way to go. In fact, the interesting one here is his little brother, the ATIV Book 9 Spin:

The $1,399 Samsung ATIV Book 9 Spin has a 13-inch QHD+ display that can rotate 360 degrees, turning this notebook into a tablet.

Not bad for a convertible laptop that offers the same specs minus the discrete GPU and that gimmicky screen. The resolution here (3.200 x 1.800) is nice and the format, with a 13.3 inches diagonal, is much more interesting for users that demand more portability.

Please tech, don’t bore me

If you pretend to be succesful in technology, you have to surprise us first. Do it at any cost. Present the smaller (or bigger) next big thing, the cheapest (or even the most expensive), or the one with that technology advance that seems unavoidable.

You’ve got our attention. Now prove that feature really pays off. Which is what most businesses try to do nowadays with their new launches. It happened everyday at IFA 2015, where technology once again was a little boring. Daniel Cooper writes about that on Engadget:

Technology, as we’ve established, can’t be boring. It has to excite us, and it does that by promising to make our lives better and more efficient

He talks about 4K, but the issue here is present in any number of technologies that are boring us. 4K is one of those boring advances. It’s unfair, yes, but 4K per se is not a compelling reason to buy that next TV (or smartphone). It doesn’t make our lives much better or efficient. And that’s a big problem if you’re not Apple.

So don’t bore us. But keep trying to surprise us. Please.

TVs at IFA 2015: 4K and HDR are coming: bigger is better

Don’t buy a new 4K UHD TV set. Not yet. Wait, at least, to get the new models with HDR. They are really promising.

Oh, and if you finally decide to buy one, please keep this in mind: you’ll regret not purchasing that one that was a little larger. Don’t follow your wife’s advice on this. Trust me.
