I mean really, there is no need for salesperson involvement to buy a phone anymore in the 21st century.
I really don't understand the hand holding many consumers believe they need when buying a phone.
Its not rocket science, its a phone. Pick a platform, if you don't know what platform to get (Android, iOS, Microsoft, Blackberry), then just buy an iPhone. Apple has the best marketplace of any of them and the average user wants to play Angry Birds on a phone without having to find out their platform doesn't have the version of Angry Birds they want to play. Apple has them all.
Also this is the one market where Apple is on par with pricing. EVERYBODY sells phones for wayy too much money, so if you need to hound a salesperson for a hour just to save $25 off the price of a $800 phone, you are a time waster.
After all that, there is only one plan to get. Unlimited data, text, calling. $50/ mth, period. If you can't or won't pay that much, then don't buy a smartphone. All carriers have the same plan for the same price there is no need to talk to a salesperson hoping for that one sweet plan that nobody asks about or is advertized.
Also Apple can make buying a phone easier by ending the stupidity of having phones with different storage capacities. It costs like $0.50 for 64gb of flash memory these days so just deck the phone out with as much memory as you feel you can make an insane amount of profit off of and sell one version of the phone so consumers don't have to ask a salesperson how many songs, pictures, and movies it holds. Besides, its all in the cloud these days so you do not need to have 6 years worth of continuous music stored on your phone.
Finally, MOST people these days buying a cellphone are buying a replacement. If you didn't understand the process of how to buy a phone and pick a plan the first 3 times, maybe you shouldn't be buying the phone.
So, just put automatic iKiosks in every mall in the country that has a credit card slot in one end and spits out an iPhone in the other.
