Lenovo's Miix 510 laptop/tablet hybrid is a solid alternative to the Microsoft Surface Pro at a much lower price.

Oh look, another top-spec tablet with detachable keyboard and pressure-sensitive stylus. Must be a new Surface Pro, right?

I bought this product and used over a year. It is good initially, as the days passed cooling fan noise is not bearable and some hardware and technical glitches started up after certain updates.

The 2-in-1 tablet hybrid is certainly no longer a novelty. The market is now flooded with devices with detachable keyboards that offer up Windows 10's capabilities as a tablet and desktop OS. And, of course, there's the small matter that Microsoft makes a couple itself.

Beats Surface Pro 4 on price; Has USB-C as well as USB 3.0; Included keyboard cover

No microSD; Charger should be USB-C; Average battery life

Close to matching the Surface Pro but at a fraction of the price, perfect for my son starting uni!

By matching the Surface Pro in almost every area, the Miix 510 is a fantastic alternative to Microsoft's killer convertible. It's cheaper, more powerful, and has a keyboard in the box, instead of making you buy one separately. It's not perfect, though. The screen resolution is lacking, and that keyboard hints at how Lenovo has managed to keep the costs down. You've still got to carry a power cord around with you, too - not just because battery life is only average, but because it doesn't use USB-C to keep charged up. Still, if you've been eyeing up a hybrid but couldn't justify spending all that cash on a Surface, the Miix 510 is a great buy.

Latest-gen CPU means snappy performance; Bundled stylus is a nice extra; Works great as a tablet, and as a laptop;

It’s alarming that Lenovo has managed to get quite as close to the Microsoft Surface Pro 4 at half the cost here. High-quality build, a good screen, solid performance and a comfortable keyboard mean there’s nothing to let the side down and make the Lenovo Miix 510 seem cheap or compromised. Not every part is as good as the Surface Pro 4, of course. The Microsoft keyboard is a little stiffer, the screen is much sharper. However, the two laptops have exactly the same functional benefits and the Lenovo Miix 510 is also competitively-priced next to more conventional slim laptops. The main point to mull over is battery life. At 6.5 hours with light tasks, the Lenovo Miix 510 won’t last all day long. Consider that everything is crammed into a 10mm-thick shell and it’s no great surprise, though.

The Surface Pro 4 's combination of a solid OS in Windows 10 and elegant hardware made it the first tablet PC to live up to Microsoft's message that a tablet really could replace a laptop. So if you were going to design a 2-in-1 tablet, it would make sense to emulate one that works, right?

The good-looking hinged kickstand has a lot of positioning flexibility; Has a USB-C port for video output and peripherals with adapters; Unlike Microsoft, Lenovo includes a generally excellent backlit keyboard cover; Lenovo's Active Pen and palm rejection work very well

The fans can get a little too loud for quiet environments; No memory card slot for expansion; The Active Pen is a $40 extra and its included holder blocks the power jack; The tiny right-hand shift key is horrible

A 2-in-1 following in the footsteps of the MS Surface Pro 4 will likely be compared to it. Lenovo's convertible features better connectivity and a better SSD, but the display and the cameras are lacking.

good keyboard; Type-A and Type-C USB; sturdy; upscale construction; option for LTE; usable main camera; good microphone

display not very vivid; PWM at and below 90 % brightness; fan always on during idle / when connected to power; no monitor-out; mediocre webcam; battery life not that great
