Brydge announces its latest Stone Pro Thunderbolt 4 dock alongside the SP+ Surface Pro 8 keyboard

Brydge might be best known for its alternatives to accessories such as Microsoft's Signature Keyboards. Accordingly, its latest such product competes with that first-party add-on for the Surface Pro 8. This new SP+ Wireless Keyboard with Touchpad is depicted as having a design that can hold the tablet up without the need to resort to a kick-stand, yet supports viewing angles of up to 180°.

Brydge asserts that it can turn the Surface Pro 8 into a true laptop replacement with its "precision" touchpad and backlit keys. Then again, without a fingerprint sensor, a pen or a silo for the same, it is the best match for the cheapest version of the latest Signature Keyboard.

It comes in at US$180, whereas the Bluetooth 5.0 Brydge SP+ is now set at $140. It comes in Black or Platinum aluminum with an anti-microbial treatment, as opposed to Alcantara in a greater range of colors. The Stone Pro TB4, on the other hand, comes in just 1 dark gray colorway, and also with a total of 12 additional port and support for up to dual 4K monitors.

The new USB type-C dock also supports pass-through charging, albeit only up to 90W. It does, however, obviously offer up to 40Gb/s transfer speeds, running through "a sleek high-grade" form-factor. The Stone Pro TB4 is now available to order for $349, although it may not ship until November 2021.

This applies to Brydge's own store, although it and the SP+ is slated to join its TB3 predecessor on platforms such as Amazon eventually.
