Considered to be the first media tablet paired with a 4G mobile broadband network earlier this year, news comes today that RIM and mobile carrier Sprint have agreed to drop plans for a BlackBerry PlayBook tablet incorporating WiMAX.
The balance of 3G/4G-enabled PlayBook launches expected during the second half of 2011 -- including HSPA andHSPA+ 3G models -- are still considered to be "on track" for carrier introductions. RIM says it is focused on bringing an LTE model to market as well.
WiMAX hasn't fared well in the slate form-factor to date. Remember the Nokia N810 WiMAX Edition or Samsung's Mondi? The sole media tablet left standing with WiMAX is the HTC View 4G, also on the Sprint network in the US.
