Alternatives

Our verdict

Based on the evidence, this suits budget buyers who want a big, light-for-its-size screen and a modern Wi-Fi chip. It lacks a touchscreen, a backlit keyboard and Ethernet, and we could not confirm UK price or real-world battery life. This is a research summary, not a test result.
