Categorizing device types by desktop, mobile and tablet no longer works in 2021. It is oversimplified, meaningless and likely breaks your current performance analysis on a modern responsive website.
As #perfmatters we need meaningful monitoring that takes into account the modern web:
- Screen dimensions
- Device pixel ratios
- Image and CSS breakpoints
- Connections
Keeping it both simple and meaningful is however not easy! Learn about the different approaches and how to apply this to your existing RUM monitoring solutions: be it free (Google Analytics), open source (Boomerang) or commercial.
