Yes Susan I understand all that... I know 'how' and 'why iOS 8 Requires So Much 
Free Space To Download and install OTA ;-)

"When you’re downloading a new system update like iOS 8, all the contents are 
stored in a compressed file. Once the download is complete, your iOS device 
will start unpacking that compressed file. Your iDevice needs enough storage to 
both handle the compressed file and all its uncompressed contents as the system 
reboots.

In addition, it needs to be able to store the previous system version — in this 
case, iOS 7 — while the compressed system update and its uncompressed contents 
initialize and take effect.

Once the update is complete, obviously, iOS 7 and the compressed file of iOS 8 
will disappear, thus freeing up space on your iPhone or iPad again. At that 
point, you can reload your device with all your movies, music, and apps, which 
you hopefully backed up to your computer or the cloud."

And it is quite possible that Laura has enough Available Space to install and 
use iOS 8 after she downloads and updates via connection to iTunes.

She has not said how much available space she has on her iPad.

I hope that ends this 'debate' and we can wait and see if Laura has success or 
not.

Cheers,
Ronni
