I have received a donation for a blind teen of limited means.
This donation is enough to either by the iPhone 5S with 32GB and 4 hours of VO traning, or an iPhone 6 with 16GB.
I'm willing to donate the training time myself, but I'm still debating the storage space vs. the better processor.
With 16GB she will be struggling to make space on the phone all the time, deleting things to make space for new apps and media.
With the 5S she'll suffer from lag, especially once IOS 9 comes along in half a year.
I really can't make up my mind.
