Overview

The Microsoft Arc Mouse solves a specific problem with genuine engineering cleverness: it delivers a fully functional, ergonomic wireless mouse that collapses to a flat slab thin enough for a pocket. The snap-to-curve mechanism serves as both the ergonomic shaping and the power switch — curve it to work, flatten it to stow and power off. Once curved, the touch-sensitive surface replaces a traditional scroll wheel with a full plane that registers vertical and horizontal swipes, a meaningful advantage for anyone navigating wide spreadsheets, design timelines, or multi-column layouts. Bluetooth 4.0 handles connectivity without occupying a USB port, and pairing is straightforward across Windows and macOS.

The trade-off for this portability is clear: the Arc Mouse is not built for eight-hour desktop marathons. Its low-profile curve provides enough palm support for productive sessions on a train, at a café, or during meetings, but it cannot match the sustained comfort of a full-size ergonomic mouse. Tracking is handled by a standard optical sensor adequate for productivity tasks on most surfaces. At roughly 2.7 ounces with batteries, it vanishes into your travel kit. For mobile professionals who need a real mouse — not a trackpad compromise — without surrendering any bag space, the Arc Mouse remains one of the most elegant solutions available.

Pros & Cons

👍 Pros

  • The snap-flat design compresses to just a few millimeters thick, slipping into a laptop sleeve pocket where no conventional mouse would fit.
  • Full scroll plane enables both vertical and horizontal touch scrolling on a single surface, eliminating the need for modifier keys when navigating wide documents.
  • Bluetooth 4.0 connectivity pairs without a USB dongle, preserving the single USB port on ultrabooks and tablets for other peripherals.
  • The curved ergonomic shape, when snapped open, provides a comfortable palm rest that belies the mouse's ultraportable footprint.
  • At roughly 2.7 ounces, it's one of the lightest full-function mice available — barely noticeable in a bag or coat pocket.

👎 Cons

  • The low-profile curved shape lacks the tall palm support of a full ergonomic mouse, which can cause fatigue during extended desktop sessions exceeding a few hours.
  • No USB dongle option means devices without Bluetooth 4.0 — including many older desktops — cannot use this mouse at all.
  • The touch scroll surface lacks the tactile detent feedback of a physical scroll wheel, making precise line-by-line scrolling less controlled.
  • Requires Windows 8 or later for full feature support, locking out Windows 7 machines and limiting advanced gesture features on non-Windows platforms.

Frequently Asked Questions

It supports Mac in addition to Windows 10, 8.1, and 8. The Bluetooth 4.0 connection pairs natively with macOS — no proprietary dongle required. Some gesture customization features may be limited outside of Windows.
The touch-sensitive surface supports both vertical and horizontal scrolling with finger swipes. It's smoother and quieter than a physical wheel, and horizontal scrolling is especially useful for wide spreadsheets or timeline-based editing applications.
For general productivity — browsing, document editing, email — the latency is imperceptible. Bluetooth 4.0 is not ideal for competitive gaming or precision CAD work where sub-millisecond response matters, but for its intended use case the connection is responsive and stable.
Snap it into its curved shape to power on, flatten it to power off. There's no separate switch — the physical form factor is the power mechanism, which also prevents accidental battery drain in your bag.
It runs on two AAA batteries. Typical battery life spans several months of daily use depending on usage patterns, and the flat-snap power-off design helps conserve charge during transport.
