Dell laptop lineup for logistics technology and CAD workloads

Hi everyone,

I'm trying to better understand Dell's laptop lineup rather than looking for someone to choose a laptop for me.

My workload includes:

• Software development (VS Code, Docker, databases)
• Logistics Technology projects
• Autodesk Inventor
• Other CAD applications
• Multitasking with many browser tabs and development tools
• Storing a large amount of project files

My budget is around 15–30 million VND (roughly $600–1,200 USD).

I'm interested in understanding the practical differences between Dell's business and consumer lines, such as:

• Latitude
• Precision
• XPS
• Inspiron
• Vostro

For people who use Dell laptops professionally:

• Which lineup is generally better suited for engineering/software development and CAD work?
• Are mobile workstations like the Precision series worth the extra cost compared to Latitude or XPS?
• Are there any common reliability, thermal, or upgradeability issues I should be aware of?

I'm not looking for specific purchase recommendations—I'd just like to understand which Dell lineup is designed for this type of workload before I narrow down my options.

Thanks!
