I think you can count me in as getting one eventually :-) The SAM seems very interesting, and I think it would be very enjoyable to own and use one. Plus the idea of possibly completely replacing my PC sounds great!
The problem at the moment is justifying the cost and the best way to pay for one. I am not saying it is too expensive - the cost is relative and it costs what it costs. But, do I need to sell some of my other gear first? Save for it? Rob a bank? ;-)
Only 25 SAM's to Australia? It'll be interesting to find out!
