There is a rule, custom laptop is called programming laptop cause nearly 90% is used for projects. 15.6 inch laptop for coding and programming is usually equipped with 10th or 11th cpu, 2gb or 4gb graphics optional. 15 inch laptop untuk programming is used on big tender or group for a special jobs. 15.6 inch programming laptop under 30000 is a more competitive one for business or high school students or teachers.
However, here is the recommended laptop for programming, especially for heavy office jobs or university coursework, since double heat-releasing, metal body, bigger battery, FHD screen, high-level cpu, etc. Build the deep and stable foundation to enjoy smooth running experience. Your clients will satisfy it`s excellent performance. Of course, there are other lower specification with tight budget.
As a entry windows laptop for programming, this 14 inch celeron Education Laptop is the most competitive and hottest device for elementary project.
Any other special requirements, just contact us freely.
