There has been some controversy in recent years that Apple's iPhone continues to have a base storage level of 16GB. Many Apple fans believe this is now insufficient in 2015, as iOS takes up about 3.5GB, leaving only around 12.5GB free on a new device. App sizes have also grown significantly in recent years. This is causing problems for people who did not expect Apps to become so large. Low storage means more inconvenience when taking photos or videos, or doing something as mundane as applying an iOS patch or version upgrade. Various supplier leaks and analyst notes point to the iPhone 6S also having 16GB of base storage. For more context: http://www.macrumors.com/2015/09/03/kgi-iphone-6s-storage-16gb-64gb-128gb/ Basically, Apple's lineup looks like this (prices are full retail) 16GB iPhone 6: $649 64GB iPhone 6: $749 128 GB iPhone 6: $849 People have complained that Apple deliberately ships the base iPhone with a cripplingly low amount of storage, rather than increase the base iPhone storage to 32GB, in order to up-sell the 64GB iPhone 6, or alternatively, sell people more rental space in the iCloud. With flash memory prices as inexpensive as they are, charging $100 for a memory upgrade surely results in a hefty increase in profits. While the vast majority of people understand the business case for upselling iPhones, it has left many people feeling like Apple is not offering good value for the price increase, given the low price of flash memory. iPhones have no external storage expansion slot, so the storage cannot be expanded later. This is in marked contrast to Tesla's strategy, which is to offer a compelling product no matter what tier the customer buys. Originally, Tesla had Model S with 40, 60, and 85 kW batteries. Tesla dropped the 40 because Elon felt that it didn't give the customer a great experience in terms of range and performance. Tesla eventually dropped the 60 kW and replaced it with the 70 kW. The 60 was sort of good, but 70 is almost indisputably great. Everyone who buys a Tesla today has a great experience with the product. Personally, I think Apple is making a mistake by offering a lowest tier flagship iPhone with less than stellar storage. Making customers mad is not good in the long run, and more than a few iPhone 6 users have become unhappy with 16GB. The iPhone 6S unfortunately appears to be on its way to making more customers mad.
