That's certainly your choice, but I have a feeling many apps are going to require iOS 7 sooner than later.
I'll use the old versions, it's no problem. And until that happens, we still got about.....2 years. I doubt the most popular apps would drop iOS 6 support after a few months.
I have to respectfully disagree with you. The only thing that's hideous about iOS 7 is some of the stock wallpapers (easily changed) and some of the stock icons (easily hidden). With a good wallpaper, and attractive third-party app icons, iOS 7 is really quite lovely. I especially like the new zoom-in, zoom-out animations.
Each to their own, of course, but those blurs and zoom animations are not for me. I like simple things, and while not a fan of felt textures and yellow skeumorphic note-taking apps, I do like the linen background texture of folders and the glossy dock way more than iOS 7's attempt. And the icons, of course.
