Free MicroSD card?
I think the most interesting thing about that article is the reference:
Samsung also notes that users who really need more storage space than the Galaxy S4 readily offers can turn to external solutions, and it has made things somewhat easier for them by bundling a free microSD card with every unit “for extension of memory.”
I got my S4 as a preorder from Sprint and was surprised to see that the retail box did not contain an SD card. Perhaps it was cleverly hidden in the box and I missed it?
