IMO Blackberry must release the S4 sized Blackberry with even better spec's than the soon to be released Samsung S4.Yes the 4.2 inch form factor of the Z10 is applealing but dont under estimate the importance of a larger screen smartphone which is on the rise in the consumer world.Many larger sized phones are popular with the over 40 crowds for one reason only,their eyesight dictates the need for the larger screens.Its actually better for most and the cost of the larger devices is no different then the smaller sized phones.The 4.7 -5.8 inch smartphones seem in many minds more bang for your buck!!.The browsing side of these phones makes the overall experience much more enjoyable.Hopefully Blackberry releases the ZX10,which is my name for their next NEW SUPERPHONE.>
