I don't think you should view BitCoins as a replacement for "real" currencies just yet as the article implies. You should see it as investing in gold (but safer since we know exactly how many bitcoins there are). Being able to send money anonymously is it's core value.

Not really, the trace only tells you coins were exchanged between two BitCoin wallets, not who those wallets belong to. And any person can have an unlimited number of wallets so even impossible to tell how much one single person has.

Deflation means that the price level of goods and services is going down. There is nothing built into BitCoin that forces you to lower the price of a service you are offering. The argument of "my money is worth more" is flawed. Let's say that the value of a single bitcoin increases from $10 to $20 over a year. That doesn't mean the BitCoin economy deflated - it just means anyone who bought a BitCoin a year ago made a good investment. The cost of a service can still go up.

Not true. The major owners in Apple, as any major company on the stock market, are mutual funds and institutional holders with 72% of the stocks. Maybe the majority of the small time investors are emotional, I don't know, but that is a completely different thing since they can only affect the stock price so much.

Cell phone networks already support multicast so there is no need to hade individual streams to each handset. The standard is called MBMS and is part of the GSM/HSPA/LTE standard.
