SAAB's JAS39 Gripen uses nosewheel brakes, along with extreme nose-down canard position to increase nose gear reaction loads. Consequently the nose gear looks pretty beefy for such a small airframe. With relatively demanding STOL requirements the penalty was considered worth paying.
I'll add a (6) to Genghis' list of negatives:
(6) reduced nosewheel steering effectiveness - the more braking is employed, the less sideforce the tyres can generate.

this article:
The Gripen automatic landing mode triggers at nose wheel ground contact, and provide large deflections of canard, elevon and air-brakes and also application of a nose-wheel brake, as deceleration means.
(Although not mentioned, I'm sure mainwheel brakes figure in the mix too)
