MojoKid with word of The Stack, a new peripheral product from Lenovo that has a ThinkPad logo emblazoned on each component, writing In a nutshell, this is Lenovo's take on a line of peripherals that all work with one another and stack together via a custom connector. It applies the modular computing concept to the world of peripherals, which could be an ideal place for a set of modular products to actually make an impact in the market. The Stack's initial four products include a wireless router, a 1TB USB 3.0 hard drive, a Bluetooth mic + speaker combo unit, and a 10,000mAh battery pack / charger. The foursome is sold for just under $390, though each component can be purchased separately as well. The sheer size and weight of the package is impressive. While it's appropriately dense, it can fit into even the smallest saddle bag, taking up minimal room in a frequent flyer's carry-on. In testing, the Stack's individual components offered respectable performance results as well.
