Lenovo Yoga C740-14: Great mid-ranger but with spongy keys
Higher-end convertible laptops like the Dell XPS 13 7390 2-in-1, Lenovo Yoga C940-14, HP Spectre x360 13, or the Asus ZenBook Flip 14 are great if you're willing to spend over $1000 on them. Once you start moving down to the lower-end models, however, the appeal quickly dwindles because these cheaper systems tend to be thicker, uglier, and heavier. At that point, the 2-in-1 form factor would no longer be as practical.
The 14-inch Lenovo Yoga C740 is a notable exception because it manages to retain the lightweight and sleek design characteristics of some higher-end models while costing hundreds of dollars less. If you want an affordable convertible subnotebook that's not too bulky or unwieldy to use, then this aluminum-clad Lenovo will be one of your better options.
Of course, some drawbacks are present in order to keep costs low. The system is missing a few luxurious features like Thunderbolt 3, a super-bright display, 4K UHD options, and a wide color gamut. For such extras, you'll have to consider the pricier Yoga C940 instead. What we can't forgive, however, is the spongy keyboard keys. Lenovo ThinkPads have some of the best keyboards on any current Ultrabook in terms of travel and tactility which only raises our expectations for the consumer-centric Lenovo Yoga series. Instead, what we have on the Yoga C740 is a keyboard with weak feedback and shallow travel more reminiscent of a cheaper IdeaPad. It's certainly an aspect Lenovo could improve upon for future iterations to make the Yoga C700 series an even better mid-range convertible.
