When they started they had a huge jump on the competition. The market has gotten vastly more competitive, I certainly hope Apple would try and change their strategy to stay competitive.
Those people already wouldn't be able to do anything with the phone with gloves on once it's unlocked anyway. They already make special gloves to work with touchscreen.
Apple doesn't compete on price.Look at computers and iPods.No sign of that changing.
And so far they are doing pretty well.
