Same here. I've never purchased the latest and greatest.
Recently though, I've grown to respect Steve Jobs more than anything (I've always respected him, mind you, just more now). I am a loyal person to people (and products) who are good to me or who've shown that they stand up for what they believe in. Thus, I want to switch to an iPhone. I currently have a Samsung Galaxy S2 that works great...but I'm feeling like I want to follow Steve Jobs creation. He pioneered the way for all other phones and I'm beyond proud of that.
Of course, I don't plan to keep switching phones. I just want to pick an iPhone and stay with it. But, if the iPhone 6 will have more than 8 mpxl for its camera, I think I might have wait for it.
