The W Series are designed to be the minimum of what you can expect from the eInk devices by Senitrus. In addition, they will also be the cheapest which is good considering you would be getting just the bare essentials. You will get 4GB of memory, 8GB of storage, and no cellular, but instead wifi?-7 capabilities.
The device series will come in a 7″ reader, and an 11″ tablet with a basic stylus. The stylus will have a pointy bottom tip which is used for writing. The top tip has a soft enplacemnet for an “eraser”. Towards the bottom will be button when pressed and held will highlight whatever the the pointed side is on. The stylus does not need batteries to work, but should still be taken care of.
