Why not?
So?
Why do you consider it the same?
Then don't spend it. Your Touch will function just as it always has.
How? If it's broken, get it fixed under warranty. If it works AS IT WAS SOLD TO YOU, then how is it 'screwing' you? By doing exactly what it was designed to do?
"Should" have had? Oh, I thought you were a college student. I didn't realise that you were the VP of Product Design for Apple. My bad.
Did APPLE define it as the brother, or did YOU? I don't recall ever seeing Apple marketing material that called it a phoneless iPhone, it's called an iPod that happens to have some additional features. You BOUGHT an iPod that happened to have some additional features. If you expected more, then that's your fault. It performs exactly as advertised. You knew this when you bought it. No promises were made for any additional apps.
Now, Hey! Here's some new Apps (if you want them). Cost for these apps = $20. So, you make a choice: are they worth $20 to you? If so, spend it. If not, don't. Nothing has been taken away from what your touch already does. No promises were broken. Get over it.
I am SO SICK of all the whining about this keynote and its products, and in general, all of the whining about how Apple is out to screw people.
