The Acer Aspire 5 is generally less expensive and may offer a solid performance for day-to-day tasks and some level of multitasking. However, the Lenovo Flex 5's higher price tag often comes with added versatility, such as a touchscreen and 2-in-1 capability, making it suitable for users who benefit from a tablet mode for presentations or creative work. The Flex 5 is typically more portable due to its smaller size, but this can also mean a smaller screen size for multitasking and entertainment. The Aspire 5, on the other hand, provides a larger display which may be preferable for extended work sessions or watching media. Battery life can vary, so consider the typical use case: if you're often on the go without access to power outlets, a longer battery life will be important. When it comes to performance for more demanding applications like 3D modeling, machine learning, or gaming, you may find that either laptop could be limiting if their specifications don't include a dedicated graphics card or high-performance processor. If you engage in engineering tasks or similar demanding applications, investing in a higher-end device might be necessary. Give Feedback

Sascha Mölck | November 2022
"The Acer Aspire 5 15 is a good value office laptop with reasonable battery life. The combination of slim exterior, relatively low weight (approx. 1.7 kg) and 8 hour real-life battery runtime makes the Acer Aspire a truly mobile laptop. The modest Tiger Lake processor supports this area and simultaneously ensures an affordable price point. The Aspire produces little noise and stays cool. The screen (FHD, IPS) might not win any prizes but is entirely appropriate for the price."

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."
