Sask also has our own network, and it seems to help things a lot. Been a while since I've shopped for plans, but there was a time when the big 2 charged about 25% less in Sask because they had to compete with Sasktel. They've also got their own MVNO now, Lum Mobile, which is the first to have a vastly different pricing structure than the other options. Buy 3 month/1 year plans up front, and the data bucket is an until you use it thing instead of being a monthly bucket. For about $450 (including all taxes/fees) I've got my cell service paid for the whole year, and will probably still have some data left to carry over then.
Supposedly there's been some big discounts coming around with the newer MVNO's, but its hard to gain traction when people are so used to just walking down to the nearest carrier store for phones/plans, and often choose an expensive monthly plan over buying their devices up front.
There’s going to be some variance depending on how a person tends to listen to their music. I think the decline of CDs correlates pretty well with digital options being available, and people making the switch. There’s always going to be people at the head of the pack using the new thing and people that want to save costs by keeping what they’ve got. The accessory market affects that too, there was overlap when people would have portable digital music players, but still use optical disks for their home stereo and vehicles. But as manufacturers came out with solutions like iPod docks or Bluetooth streaming the digital devices were able to push out the physical media.
