I had gotten all kinds of excited when I saw this (USB powered? Can use on my laptop? WIN!). But then I took a better look at the hashrate, and then compared that to the hashrates that are being generated by people with more cash and/or better equipment. Sure, this is good for someone just coming into BTC and looking to get their feet wet, however for the price that they are asking, I'd rather just buy LTC outright and work my way from there.
Now if they (or another developer) could come up with a similar device that would be more affordable, then I would be all over it like wolves to raw steak.
