Limited hardware is exactly why it is usable. Many e-ink devices exist now so limiting factors such as refresh rates etc, need to be considered when developing apps for android etc nowadays.
They might be maining that it requires a specific ereader model rather than being generic, but I'm not sure that really applies either. Kindles, even any specific single model of kindle, are generally readily available.
