The Surface Pro alternative. Faster than the fastest Surface Pro and cheaper as well, the Lenovo tablet returns with Kaby Lake-R to boost the Miix family back on top.

Overall, the Lenovo Miix 520 2-in-1 laptop does the job if you’re using it for basic work such as something for school, watching videos on YouTube or Hulu, or a work conference with Skype. The increase in price doesn’t seem to match with the upgrades made over last year’s model, which might turn some heads away.

Intel's eighth-gen Core i5 processor breathes new life into Lenovo's midrange detachable two-in-one to make the Miix 520 an excellent choice for home office and students.

The Miix 520 has some downside that would be deal breakers on their own but as an entire package, they’re a small penance to pay for power, speed and portability. OEMs are getting hip to how to package their 2-in-1’s and including the pen and keyboard allow for a lot of patience and forgiveness when encountering noticeable issues such as fan noise or device weight. For as little as $869, users get as close to a $1,400 Surface Pro experience as possible. In everyday use the Miix 520 is a solid device offering a great package for a reasonable price, however, for anyone spoiled by the Surface Pro or other feature packed 2-in-1’s, the Miix 520 misses the mark. I found the Miix is a recommended device for anyone in an office setting tethered to an outlet and looking to occasionally port the device to nearest conference room for a quick meeting.

The name “Lenovo,” to me, still implies thin black slabs of productivity. And while it’s true that the Miix 520 never aspires to be flashy, it’s an unobtrusive Windows tablet that sparkles with the occasional flash of luxury.

Lenovo's IdeaPad Miix 520 is an outstanding Windows tablet in terms of price and performance, held back only by shorter-than-expected battery life.

However, cash rules everything. If you want as much raw horsepower as your budget can allow – regardless of the quality of life extras and battery life it costs you, the Lenovo Miix 520 is for you. Just $999 a for an Intel Core i5 processor, 8GB of RAM, 256GB of storage and every accessory you need is a steal. Compare that price to the $1,557.99 a 2017 Surface Pro with similar specs, a Signature Type Cover and a Surface Pen would cost you, and the savings is almost unreal.
