Maybe I'm in the minority, but I don't need the iPhone to "wow" me anymore. Ever since the iPhone 4S, I've been sufficiently "wowed." Apple could cease to innovate and I would be fine for a long time. Really.
Today, my iPhone is the computer in my pocket: it's the tool that lets me email, do word processing, sync with my computer, store files in the cloud, shop online, play games, browse over half a million apps -- it's my camera, HD camcorder, calendar, the list goes on.
Last week, my home-modem stopped working. For a couple days, my iPhone was my family's gateway to the internet thanks to WiFi hotspot mode. And it's also my phone.
All I have to do is reflect on how it used to be. I was that guy who tethered my Nokia cell phone to a Palm IIIc back in 2000 using a custom cable I found online. I remember spending hours on the phone with Verizon's level 2 tech support until I could once-and-for-all configure my phone and PDA properly so I could access the web. I'll never forget what a thrill it was to be able to send an email to my Uncle in Korea from my tethered PDA while walking around the Ontario Mills Mall in Southern California.
I hope Apple and its competitors keep pushing the envelope. Keep improving battery life. Keep making Siri understand me better. Improve the maps. I still want my flying cars, robotic housekeepers, and my vehicles to run on garbage but when it comes to innovating my iPhone, I'm content.
