Earlier quoted context omitted.
That high-end / low-end thing is mostly a marketing BS invented to maximize manufacturer’s profits. Works OK in the sense their profit is fine, but if you’re a consumer, you better rely on the specs only and ignore the marketing.
Specs dont matter much anymore. Any dual core laptop can do what most people need. What matters is the build quality, QA, battery life, screen, heat dissipation. All things you cant infer solely based on specs.
If you buy a laptop to watch youtube and read e-mails, sure, any dual core will do, but for a professional, performance matters. Speaking of performance, I wouldn’t buy this dell because the CPU has no L4 cache. Some tasks, like compiling C++, benefit a lot from that 64-128 MB on-chip DRAM found in some previous-generation CPUs.
Specs still matter. Battery life is measured in hours; screens are measured in pixels, inches and percentage of Adobe RGB.
