I just don't see the point of waiting. My sleep button is semi functional and it just bugs me. If the 5s really interests me when it comes out I'll just sell my 5 and buy the 5s.I have 5. Girlfriend and others have 4S.
Trust me, theres not much difference,
9mbps HSPA+ to 50mbps LTE sounds big, but when using it? Maps, webpages, meh.
camera is about the same
Same pixel density
Both dual core, and 4S doesn't struggle with any apps... So.... Meh
My 5 looks great on paper. And it was a great upgrade from a 4: but compared to daily use on a 4S... Meh.
