I recently got my hands on a new demo Lenovo X1 Yoga, a kind of hybrid of the commercial ThinkPad lineup and the innovative Yoga consumer machines. \u00a0The standout feature of the X1 Yoga is its 14\u201d 2560x1440 organic light-emitting-diode (OLED) display. One of the benefits of OLED is that the panel can be thinner (generating its own luminescence, it doesn\u2019t need a backlight), allowing an even svelter profile. \u00a0The X1 Yoga \u2014 which is a full-on workhorse notebook with an Intel Core i7 processor \u2014 is only 16.8mm thick.\nBut the most spectacular benefit of the OLED screen is its\u00a0rich color palette, including the deepest of blacks. Images truly pop. And video looks like you\u2019re at the movies in a really dark theater. \u00a0This magnificent panel does come with a minor downside, though, which is a slight drop in battery life. Lenovo specs the OLED model out at 9 hours, whereas the regular backlit LED versions can make it to 11. Still and all, it\u2019s a tradeoff I\u2019d make without looking back. \u00a0There are various power-saving schemes you can use to squeeze some more life out of the 4-cell 56-watt-hour lithium-polymer battery, but there is an energy cost to all that visual loveliness.\nThe Lenovo online configurator gives a list price of $2,554 for the beefy config I\u2019m testing, but with \u201cinstant savings,\u201d it slides in at $1,915.50, which, although a serious chunk of change, is actually not all that much for the i7 model with 16GB of 1866MHz LPDDR3, a 512GB SSD, and the aforementioned incredible OLED display. \u00a0So, this is really not your take-it-off-to-college-to-bang-around-and-take-notes kind of notebook. \u00a0It\u2019s really more of a I\u2019ve-finally-arrived-and-deserve-the-very-best sort of notebook.\nLenovo\u2019s X series has always been the lightest of the ThinkPad line. It was designed for those who want top performance and don\u2019t need all those legacy things like optical drives, Ethernet ports, and media card slots. \u00a0The T series is the kitchen-sink model, for the man who needs everything. The Yoga has been distinguished as the most flexible of the Lenovo family. It\u2019s the one that bends and folds in any direction like an advanced yoga instructor. \u00a0The Lenovo X1 Yoga bridges both worlds.\nThe 360\u00b0 hinge on the X1 Yoga isn\u2019t the fancy bracelet type seen on some of the consumer models. \u00a0It has the more sober corporate look of buffed steel. \u00a0But the thing still bends and twists like Houdini, acting like a tablet in one mode (complete with included stylus for more-accurate touch input), \u201ctent\u201d in another mode (for video chat and other social activity), "stand" in a third mode (for video viewing on airplanes), and normal notebook mode (for regular work activity).\nFor old guys like me, the high-resolution panel can lead to difficulty reading the tiny text that results, but Microsoft has implemented a decent Windows 10 utility that allows the user to resize text for legibility. \u00a0The default on this machine was set to 125%. \u00a0I cranked it up to 200%, and now everything is fine.\nVanilla Intel HD 520 internal graphics run the fantastic panel. With 8GB of graphics memory, this setup has enough juice to power most visual tasks. \u00a0This is not a gaming rig, and adding external graphics would expand both the heat envelope and the physical space requirement, which would ruin the system\u2019s sleek profile.\nEven though it has some of the flair of the Yoga consumer line, the X1 Yoga is clearly a business system. \u00a0It has a TPM security chip and optional Intel vPro remote management suite. With optional adapters and a WiGig dock, the notebook can manage various legacy I\/O, like Ethernet and VGA, as well as additional USB ports. \u00a0And it is always worth mentioning the Lenovo keyboard, which sets the standard for the industry. \u00a0The travel, feel, resistance, and feedback are second to none. In tablet mode, the keyboard retracts fully into the body.\nWhile the X1 Yoga is a serious system for business use, it does have enough solid media characteristics for after hours at the hotel or that long plane ride back across the country. All in all, it\u2019s one of the best premium-class systems on the market.
