Coming from a Samsung Galaxy S (which totally sucked). Very pleased with the 5s, have a space grey. Chick just got a silver 5s. The 5s sounds great, which is most important to us, we actually use it as a phone.
TouchID is working. Phone works. Decent signal strength, wifi and bluetooth pairing to automobiles was flawless, have not had a single dropped call or wifi problem/issue.
iOS7 is pretty good. I like the way the phone handles favorites, recent messages, contacts, calling/speakerphone/conference calling, and the visual voicemail works like a charm. 16 GB was plenty of space for us, apps are working fine, screens are good, touch screen is good. I know some peopel complain about it, but I actually have found Apple's keyboard and typing correction to be pretty darn accurate and speedy.
Really, no complaints. We bought unlocked Verizon 5s (a ton of them for the office), everyone is now using them on GSM networks, I'm on T-Mobile, just dropped in a T-Mob nanoSIM and bam, up and running in literally two minutes. It's a true world phone, we can take it anywhere in the world and we are good to go on many, many carriers.
Very pleased with the 5s, a great product and this will likely be our phone for many years.
