Samsung defended the phone this week. "For the Galaxy S4 16GB model, approximately 6.85GB occupies [the] system part of internal memory, which is 1GB bigger than that of the Galaxy S3, in order to provide [a] high resolution display and more powerful features to our consumers." The company then added, "to offer the ultimate mobile experience to our users, Samsung provides [a] microSD slot on Galaxy S4 for extension of memory."
This may be true, however, Samsung only allows you to place content on the SD card, not all applications.
Microsoft caused a stir earlier this year when it was revealed that their 64GB Surface tablet had only 29GB of usable space. The 8GB Nintendo Wii U is even worse,leaving just 3.3GB available.
