The fly in/out wasn't the problem for me, it was the parallax effect that was making me dizzy. True, some people say I'm dizzy already, but no, I'd get really woozy, urpy, sit and be still dizzy. Turning my head fast was making it worse, and I flew in the very beginning days of iOS 7, and that made it worse too. I still detect some parallax from time to time, like the weather app for one, although it's primarily right to left...
I find it odd that none of the Apple development team thought that it might be an issue. It's nice that they don't suffer from vertigo, and I sure wish I didn't too. I nearly ruined a vaca to Puerto Rico one year early on in my discovery of vertigo by snorkeling with some friends kids, and just inverting head down trying to reach the bottom. I had an awesome day doing that, but by the next morning I was bouncing off walls trying to walk a straight line! It was NASTY! The weather turned very nasty, so all I did was sit in the bar and try to acclimate to level terra firma, but it wasn't easy. A friends grandfather had vertigo so bad that if he got up from the couch too fast, he'd do a face plant. I hope that's not in my future... Yippee...



----------
iOS 7.0.3 update does this:
This update contains improvements and bug fixes, including:
- Adds iCloud Keychain to keep track of your account names, passwords, and credit card numbers across all your approved devices
- Adds Password Generator so Safari can suggest unique, hard-to-guess passwords for your online accounts
- Updates lock screen to delay display of "slide to unlock" when Touch ID is in use
- Adds back the ability to search the web and Wikipedia from Spotlight search
- Fixes an issue where iMessage failed to send for some users
- Fixes a bug that could prevent iMessage from activating
- Improves system stability when using iWork apps
- Fixes an accelerometer calibration issue
- Addresses an issue that could cause Siri and VoiceOver to use a lower quality voice
- Fixes a bug that could allow someone to bypass the Lock screen passcode
- Enhances the Reduce Motion setting to minimize both motion and animation
- Fixes an issue that could cause VoiceOver input to be too sensitive
- Updates the Bold Text setting to also change dial pad text
- Fixes an issue that could cause supervised devices to become un-supervised when updating software
So I assume that there might be other tweaks they added to it. I set bold text too and it made iOS 7 a whole lot easier to live with. It looks less 'cartoonish' IMO. YMMV...
