If you have customers that see you as adequate you will keep customers based on inertia.
But you have several big problems awaiting you. Those trying to win your customers business only have to overcome inertia – which can be very low hurdle (saving a small bit of money, some minor additional feature). If your customers are delighted they won’t leave (by and large) without significant reasons to.
Also your attempts to increase price are very likely to lead to increased customer losses (than if customers are delighted). Delighted customers are willing to pay a premium which helps profits enormously (Apple has done this quite well).
Delighted customers will refer others to you – great free marketing.
Satisfied customers leave you very little leeway for error. If you cause satisfied customers some problem (which granted, hopefully you won’t but if you do) they are not likely to be forgiving. If they are delighted they may well stay even if you have a delay, provide less than stellar customer service for some request…
