The change from software-only to hardware can have a great impact. That's a very interesting observation of yours.

Funny you say that. I'm going to buy Walden today :)

That's an accomplishment reserved only for the enlightened ones. Maybe you're onto something :)

I think those are the real accomplishments.

Great work! You should add some sort of social sharing widget.

Thanks! Yes, I should do that :-)

MacGuyver or MacGyver?

Very cool!!!

About the pseudo credit card, in Portugal (where I'm from) we have a system called mbnet [1] where any portuguese bank account owner may create a temporary credit card. I usually use it for buying things online. This card has some security restrictions: you can specify if it's going to be used for 1 or more transactions and the top amount of the transaction. It works pretty well.
