TOM BIHN today announced it has created the new Size 4X of its hard-shell Brain Cell (US$50.00 — shipping February 15th) and Monolith ($45.00 — shipping February 28th) laptop cases specifically for the 15.4″ MacBook Pro. “The Brain Cell (available in eight sizes, including Size 4X) and Monolith (available in five sizes, including Size 4X) laptop cases take laptop protection a step further. Cradled in 8mm thick soft foam padding, the laptop hangs suspended in a 4mm hard corrugated plastic insert that protects from the front, back, and bottom. The sides are protected by dense cross-linked closed-cell polyethylene foam.” Both bags are available in five colors: Black, Steel, Deep Blue, Crimson, and Wasabi.
