Optimized Apps: These are applications specifically designed to run on ARM architecture. They offer the best performance and efficiency.
Emulated Apps: Applications built for x86 architecture that can run on ARM through emulation. These may not perform as well as optimized apps but are still functional.
Incompatible Apps: Some applications simply don't work on ARM architecture at all.

Current State of App Support

Well-Supported Native Apps:

Photoshop
Lightroom CC
Chrome
Spotify
Prime Video
Dropbox
Zoom

These applications run smoothly and efficiently on the ARM-based Surface Laptop.

Emulated Apps:

Lightroom Classic
TickTick (to-do list app)

These apps work but may experience some performance issues or increased battery drain.

Incompatible Apps:

Arc browser
Google Drive desktop app
VMware
Many VPNs
Numerous games (often due to incompatible anti-cheat software)

The Importance of App Compatibility

For potential buyers, it's crucial to check whether the specific applications they rely on are compatible with Windows on ARM. Depending on individual needs, the current state of app support could be either perfectly adequate or a significant drawback.

Hardware and Design
