Looks very cool - will add to my phone tonight.

I cant speak too much about mining, but Linux is certainly better for security.  Ubuntu is extremely easy to setup and use. 

 

Bitcoin offers several things right now - a way to easily send, to send money discretely, and a few others.  It does not offer free money.  If you want to invest in Bitcoin (under the assumption that it will go up in price and you will make money) you can do that by putting money into equipment and mining at a loss for the time being, or buy simply purchasing and holding bitcoins.  It is not a free money give away.

I've been following bitcoin for about 1 month.  Frankly I am pessimistic about the value in the shortterm, but cautiously optimistic about the long term future.  We just need some good ideas and some good developers. 

 

I'm not expert - but I was very suprised that it recovered from its drop to 11.  I thought for sure it would drop down into the low single digits.  Frankly, the value of bitcoin at this point is transactional, and there arent a great deal of businesses to transact with.  However, in the long term, as prices begin to stablize and/if bitcoin proves itself reliable it could become a real store of value.  I've been following for about a month now and I am very eager to watch the future.
