The Lenovo Flex 4 80SA0000US is a best selling 2-in-1 budget laptop that’s received positive reviews for its keyboard quality and its lightweight, versatile design. The 2.1GHz Intel Pentium Dual-Core 4405U processor may not be the fastest, but it eases through basic tasks according to most users. Users liked its build quality, suggesting that it feels sturdy and its touchscreen adds convenience. However, throwing heavier tasks at it saw some noticeable lag, with many suggesting that it is due to the 4GB of RAM. The 5400rpm storage drive also means slower boot and app loading times. Furthermore, while many thought the keyboard feels good, the right half-sized shift key is said to be rather annoying. Lastly, the screen is only HD at 1366 x 768, and not Full-HD. All-in-all, the Lenovo Flex 4 80SA0000US is held back slightly by its slower hard drive and 4GB of RAM, but both of these are upgradable.
