People who paid $15 or $12 a share for the great renaissance of Globalstar as GSAT only to watch the share price go to 24c would not have been thinking that it was much different from zero. In fact, when using just two significant figures like that, 24c could reasonably be written $0. Over 50c would be written $1, below would be written $0.
If you go back over the decades and thousands of posts, you will find that when preparing to make a call, the message on the phone would say "Calls are now 42c per minute, please SEND to complete your call at this price". Interrupting existing calls should not be necessary. < You preach "instantaneous pricing based on demand at that moment". When someone is making a call, text shows up and says, "Satellite is fulling up, next minute will cost you $10, do you want to continue talking? If not, goodbye. Click. >
But in major emergencies, such as 911, when everyone wants to get on their phone, a force majeure clause might be needed "In the event of a major event, you hereby agree that your calls may be terminated with pricing reset to enable people who have to make calls to gain access. You will be able to continue your call by accepting the new price." Your legal jargon, mileage and price may vary.
"Unlimited" means just that, or 30 days x 24 hours x 60 minutes = 40,000 minutes. Would we really want many people using that many minutes per month including termination charges? Perhaps 4,000 minutes a month would be near enough to "unlimited" for regular humans. That would be 1c per minute, which is a pretty cheap price. "Unlimited" would have the advantage of not having to record and report individual calls so perhaps it's a good idea - there would certainly be no dispute about "Hey, that should have been 42c not 47c for that call".
My pricing is intended to actually offer a great deal for subscribers while making money for Globalstar. Not simply to give service away to free-loaders though you might have mistakenly got that impression.
PCS, since the share price got way down below $1, the cents became germane. Not just to the nearest 10c either, but to the nearest cent. 2 significant figures is a near-enough price for me. The supersonic high speed million mile a minute computer algorithm traders look far closer than that, but they are thinking in response times of microseconds and values of 6 significant figures. 2 significant figures is okay with me and a response time in the morning.
PCTEL: Really, you are going to use the airline industry as your champion on pricing models? Sorta shoots the 'predictability' leg of your argument. IMHO, people will be drawn to a inexpensive service. Yes, some will think $1/minute is cheap and some will think it is horribly expensive. Whatever - pick you price BUT let's fill the bloody service first and then find out what that price is!
PCS, now you are doing that naughty thing of taking comments out of context. When a share price goes from $13 to 24c, that's near enough to zero for the purposes of the discussion. When a share price goes from 85c to 60c, that's quite a fainting spell. Sometimes people use percentages to get an easy idea of proportionality.
I admit to the occasional use of hyperbole, or even theatrics, not to mention exaggeration for emphasis.
