Today is the first day you can get an iPhone 6. But if you have an iPhone 5 or 4s you may already have iOS 8. The new version of Apple's mobile operating system was released at exactly 1pm EDT Wednesday. Your intrepid reporter downloaded it on a phone and an iPad to get a first look. The download took a while, I expect because everyone was trying to download it at once. Once installed it asked me a few questions about what to enable or not enable, and I was up and running in just a moment.
The first thing I noticed was... nothing. Everything looked the same. It all seemed to work the same. My apps all worked the same. I actually Googled 'iOS 8' to find out what was new.
As it happens, quite a lot. But don't underestimate the value of that sameness. It means my learning curve was going to be fairly nonexistent. I could add to my toolkit if I wanted, but I wouldn't have to jump through hoops to relearn my phone. A definite plus in my book.
