Overview
- Logitech opened US preorders this week for a limited MX Master 4 Developer Edition priced at $119.99 with shipping listed to begin in late October.
- The Developer Edition uses the same MX Master 4 hardware and specs as the standard model, including the Haptic Sense Panel, Actions Ring, MagSpeed wheel, and up to an 8,000 DPI sensor.
- The change is cosmetic: a laser-etched, developer-themed matte shell adds code references and Easter eggs such as “Hello, World,” “0xFF + 1,” and dates tied to programming history.
- Full haptic feedback and Actions Ring configuration depend on Logi Options+ and the Windows 11 haptics update, and Logitech currently does not offer Options+ for Linux users, limiting customization on that platform.
- Because the release is a finish variant rather than a tech update, current MX Master 4 owners gain no new functions but collectors and developers who want the themed styling are the most likely buyers.
