Lenovo's Yoga design has been copied by many manufacturers over the years, and if imitation is the sincerest form of flattery, then their industrial designers are geniuses worthy of the highest praise (in fact they are pretty awesome). But that imitation poses a problem for Lenovo since you've now got a host of similarly designed laptops to choose from--the HP Spectre x360, Toshiba Satellite Radius models and Asus Flips to name a few. Can Lenovo fend them off with their 4th generation model, the Yoga 900 Windows 10 convertible Ultrabook? The Yoga 900 replaces the Yoga 3 Pro, a machine whose industrial design was definitely praise-worthy, but whose Core M CPU felt less than Pro. The 900 brings back the power with Intel 6th generation Skylake dual core CPUs, and at launch the Yoga 900 is available only with the more powerful Intel Core i7. The design is very similar to the Yoga 3 Pro, and that's a good thing because it's one of the thinnest and lightest convertibles on the market. The watchband hinge is attractive and unique. Better yet, it's robust and last year's Yoga 3 Pros with the same hinge have held up well.

Design and Build

The Yoga 900 is a premium Lenovo laptop aimed at consumers (ThinkPads target business users). Thus it's more daring and stylish than the unassuming black rectangle that is a ThinkPad. The machine is available in gold and my old favorite Clementine orange as well as the duller and more conventional silver. The sides and keyboard deck are rubbery black that feels great and is grippy. Those rubbery sides are also good for absorbing impacts--if you're like me, and manage to bump door jambs and airline seat backs when toting the laptop, then this is a wonderful thing. They also create more grip and stability when using the Yoga in tent mode. Unlike a ThinkPad, the Yoga won't double as a self-defense weapon, and it will likely dent, rather than the hardwood floor, if you drop it. Again, it's not business rugged, it's consumer chic. It's not delicate, just typical of consumer oriented construction.

This isn't a seriously classy unibody machine carved from a block of aluminum like the 13' MacBook Pro or magnesium alloy like Surface Book. While it's unfair to expect a Yoga to be like a ThinkPad (different model lines, different promises), with a starting price of $1,200 and an as-reviewed price of $1,400, the Mac and Surface Book are fair competition. The Yoga looks great, but it doesn't look like the quality piece that those two do. In fact, the similarly priced HP Spectre x360 looks and feels more high end too. It's not that the Lenovo looks cheesy--anything but! It's just that materials and a high end finish (at least on our silver model) aren't where your money is going. Instead, Lenovo puts the chic into the once lowly hinge. They started with the Yoga 3 Pro that introduced the watchband hinge, and it's back here and better--it's tighter and is now silent when you open and close the laptop. It's interesting that hinges are becoming a thing--first the watchband hinge and now Microsoft's snaky fulcrum hinge. Anything is fair game when trying to jazz up a laptop without compromising ergonomics or sturdiness. The watchband hinge certainly is distinctive and striking, and more important--it works well.

The Yoga 900 feels fairly sturdy and the frame is rigid with no flex, though the removable bottom aluminum panel has some flex and the keyboard deck sounds slightly hollow when typing or thumping on the very pleasant trackpad. Again, it's not a cheaply made machine, but it doesn't exude high end. There's a payoff for the lighter and thinner panels though--this is an insanely light and thin laptop. In fact, since convertibles, aka 2-in-1s weigh even more than laptops due to more complex mechanisms and required extra reinforcement, we're even more impressed with the 2.8 lb. weight (yes it gained a few ounces vs. the 2.6 lb. Yoga 3 Pro, and that's fine with us). The Yoga 900 is so slim you might mistake it for a pure tablet at first glance. The charger is even more compact and light vs. traditional laptop bricks. It's a portable lover's dream.

Cool Customer

The two internal fans and airy spaces inside mean the Yoga 900 is a fairly cool laptop. The bottom gets warm but never burning hot, and it's noticeably cooler than the Spectre x360 with Core i7 when both are pushed hard with gaming or video export. The fan is silent when doing productivity work and is audible when gaming, should you push it to the limits with GTA V or Battlefield 4, but it's not vacuum cleaner loud and any slim laptop will run the fan at max speed when gaming.
