I'd guess encryption adds a layer of complexity to basic operations such as File Access etc, therefore reducing battery life. Most end-users don't store confidential data on their tablets anyway and so just don't need it. Now if you're using the device for business purposes, you always have the option of enabling encryption. They should offer to enable encryption upon initial setup, though (Might already be doing that, can't remember it quite clearly)
