You probably won't even use the power of the 5S...only by the time iPhone 6 comes out will most applications actually start using its power, and by then it will be obsolete...so unless hardcore gaming is something you're into, stick with the 5C.
Thanks! I have been all over the place today cuz of this forum, not just my thread, even canceled and now just reordered. I am excited to get this my main thing was 32gb, my iPhone 4 has lasted and will go to my husband. All I do is check email, call and text, take a few FB pics. I am in healthcare and have some medical apps that are big so wanted the 32. Thanks for being kind and helpful!
