Are there any alternatives?

The Surface Pro 7 is obviously the clear alternative. As mentioned throughout the review, the ThinkPad X12 Detachable has some advantages over Microsoft’s tablet, including price — the Surface Pro 7 is $1,400 (not on sale) for a Core i5, 16GB of RAM, and only a 256GB SSD, and it doesn’t include the $100 Surface Pen or $130 Type Cover. That makes the ThinkPad a couple of hundred dollars cheaper.

　　If you’re not bought into the detachable tablet format but still want a 2-in-1, then the HP Spectre x360 14 is a great choice. It’s around the same price and offers a spectacular OLED display option that’s 4K and 13.5 inches. It’s a bigger and heavier device and isn’t nearly as comfortable for inking, but unless that’s your primary use, the HP is a great choice.

　　Finally, if you don’t care about 2-in-1 functionality, then the Dell XPS 13 is an obvious choice. It’s the best laptop around and will provide a chassis that’s almost as small but provides better performance and a much better display.

　　Of course, I should mention that the iPad Pro is increasingly serious competition to Windows 10 tablets. If you’re not bought into Windows 10 or its legacy applications, then the iPad Pro is a viable option.

　　

How long will it last?

The ThinkPad X12 Detachable is durable and stocked with up-to-date components. It should provide you with years of service, but unfortunately, only the first year will be covered by a warranty. Lenovo does have several enhanced service offerings to consider, though.

　　

Should you buy it?

Yes. The ThinkPad X12 Detachable is a fine 2-in-1 that gives the Surface Pro 7 a run for its money.
