Allen Ngo | May 2021
"The highlight of the latest IdeaPad Flex 5 14 is clearly its AMD CPU. The octa-core Ryzen 7 5700U is insanely fast even when compared to the best Tiger Lake Ultrabooks in the market or even Core H CPUs in many gaming laptops. It's a lot of raw processing power for what is supposed to be a budget 14-inch convertible. If your daily workloads can benefit from extra multi-thread CPU performance, then look no further than the inexpensive AMD-powered Lenovo IdeaPad Flex 5 14. For regular on-the-road browsing or video streaming, however, a slimmer and lighter 10th gen Core Yoga, Spectre, or XPS would be a more balanced option."

Joshua Goldman | April 2017
"The 13.3-inch LG Gram is a fine fit if you need to travel as light as possible for as long as possible without spending a fortune to do it. It might not be particularly sturdy or have an eye-catching design and its webcam is less than ideal, but with its sharp touch display, comfortable backlit keyboard, responsive touchpad and a fingerprint reader for extra security, the Gram makes a respectible everyday laptop for business or school work."
