People pattern match and, moreover, we build higher level abstractions of things we pattern match often, and push the more routine parts into the subconscious parts of our brain. You probably not only read a word's shape, but probably match phrases as well and read in chunks of 3-7 words, rather than a word at a time. Even then, when was the last time you thought of how to spell a word you were typing? I'd guess you probably do it for 1 in 10 or 1 in 20 words at worst. When writing, we think in higher level abstractions of sentences and words, and our motor system is the one that does the spelling.
Read out loud to your wife (or whoever) and have them note every time you say something different than what is written in the book. You'd be surprised at how often you ad lib; your brain "filling in the gaps" while you read.
UBB wasn't about charging users for a fixed amount of downloads, it was about the big telcos charging wholesalers prices per individual, instead of, you know, wholesaling bandwidth in bulk to the independents. Basically, they wanted to impose their consumer-level pricing schemes on wholesalers, rather than sell in bulk. A big part of UBB was a change in the laws that would let the big telcos charge the independents rates based on "market value" (ie. what they charge their customers), rather than actual cost to provide the bandwidth (plus a small profit).
The big win is that the telcos still need to base their wholesale price on actual cost, rather than an arbitrary price they set based on "market forces" (ie. them) and whatnot.
Packing spheres
Spheres or balls, the problem is the same. Given this is about volume, I'd actually say balls is more accurate...
Elderly (in the way you describe them) have solutions to this stuff - it's called a map

I can't tell if you are trolling or not. Obviously no magic tech is going to make technology usable for all disabled people, but for those with limited motion in their hands and arms or poor eyesight Siri is actually a big improvement. I wasn't insinuating that Siri somehow makes blind people see or deaf people hear... You're attacking strawmen here... Do I know what I'm talking about? Well, I'm not disabled. My comment came about after a discussion w/ a disabled friend about Siri. He's not blind or deaf though.
Good to know that old people don't need a smart phone or Siri, because they have a map & yellow pages. When my grandma asks me if I know of a GPS that can handle voice navigation (not referring to Siri here), I'll tell her to get a map. Same thing, right?
