For general use and portability, the Lenovo Flex 5 14 is a strong choice with its higher resolution touchscreen, better performance, and compact design, though it comes at a higher price point. The Acer Aspire Go 15, on the other hand, offers a more budget-friendly option with a larger screen, making it suitable for everyday tasks without breaking the bank. However, it falls short in terms of performance and portability compared to the Lenovo. If you need a device for light tasks like web browsing and office applications and prioritize cost over performance, the Acer is a viable option. But for a more versatile and powerful machine that can handle a variety of tasks, including some light gaming and multimedia consumption, the Lenovo Flex 5 14 is the better investment. Give Feedback

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."
