The cheapest laptop is not always the cheapest computer to own. Compare the machine with the years of work you expect from it.
Look beyond price
Check memory, storage, battery, ports, warranty and included software.
Match the workload
Web browsing has different requirements from video editing, development or creative work.
Consider upgrades
Upgradeable storage or memory can extend useful life.
Value daily-use parts
A good keyboard, display and battery may matter more than a slightly faster processor.
