Rogers at its TabLifeTO conference this morning unveiled new data sharing plans intended for tablet and modem owners. Those with more than one device on the network can pay for a new data plan or add-on that attaches the extra device to a single pool of bandwidth. Basic pricing starts at $15 extra per device for a bring-your-own option tied to an existing plan, such as an iPad, while those buying from Rogers at the same time can pay $20 extra per month to add on the device while still claiming its hardware discount.
