Microsoft releases Bluetooth enabled universal foldable keyboard for mobile devices, lasts three months between charges, priced at $99.95

Context & Ripple Effects
This 2015 launch looks minor on its own, but it is the opening move in Microsoft's folding-hardware thread: a Modern Keyboard with fingerprint sensor followed in 2017, still Bluetooth-based and cross-platform, showing peripherals became a durable part of the company's hardware strategy.
The folding idea also migrated from accessories to computers themselves — Microsoft's own foldable Surface Duo (later discounted by $400 to $999) and third-party efforts like Lenovo's ThinkPad X1 Fold and Asus's $3,500 Zenbook 17 Fold. A $99.95 foldable keyboard was the cheap entry point to that design language.
First-order effects
- Mobile users on iOS, Android, and Windows gain a single $99.95 accessory that folds pocket-sized yet types like a full keyboard, with three months of battery life reducing the charging burden that plagues travel peripherals.
Second-order effects
- Microsoft establishes a repeatable playbook of universal, cross-platform Bluetooth input devices — the same formula resurfaces two years later in the Modern Keyboard, which adds wired mode and a fingerprint sensor rather than abandoning the approach.
Third-order effects
- If the pattern holds, 'foldable' migrates from soft keyboards to rigid displays: Microsoft ships the Surface Duo, Lenovo the X1 Fold, Asus the Zenbook 17 Fold — with the accessory market proving demand before the far more expensive foldable PCs arrive.
The trend: Folding starts as an affordable accessory category and climbs the price ladder toward foldable-screen computers, with Microsoft's keyboard-to-Surface-Duo path as the clearest example.
