The 21 Bitcoin Computer

Today we’re announcing a new kind of device for sale: the 21 Bitcoin Computer, the first computer with native hardware and software support for the Bitcoin protocol. With this pocket-sized device, if you are an entrepreneur or developer, you can now instantly buy or sell digital goods and services at the command line using Bitcoin.

...and it is a full node too.

That is quite an expensive raspberry pi

Kinda cool device though, wondering how complicated the commandline stuff is.

That device is very nice but at 400 dollars a pop it’s quite expensive, I followed the link and it would have being nice to see maybe a demo video of the device.

Very nice device but way too expensive! Who will have incentives to use this at this price?

[onemorexmr]

i really like that device.
its a little bit to expensive right now... but we need devices like this to make mining distributed

a few questions / ideas:
 - is it pool mining or solo (i'd prefer solo...but that would just be a lottery)
 - is it possible to sell that device cheaper but make it mining to your address (if you dont have direct access to that device it would still be distributed mining as you dont have a chance to harm the bitcoin network)?
 - a version with an qr scanner and a few buttons for normal shops would be nice

Ah. They finally pop above the parapet.

I can't foresee it being sold by the checkout at Walmart somehow but very interesting all the same.

I thought they'd be giving it out for free and generate revenue through mining.

I'm not sure I'm getting what is the point of this device... A Raspberry Pi with a small miner? And I don't understand why does it help app development.

Didn't know the new Raspberry accepted 128GB SD cards

native hardware ... support for the Bitcoin protocol

Where could I read more about this part?

This is amazing 

[wlefever]

This does seem pretty sweet, but I really want to learn more about it.

Developers/programmers/digital goods traders who see the benefits of the software. Buying it just to mine or run a node is not worth $400, as these are rather additional features, if I understand correctly.

Anyhow, looks really interesting.

I am not sure if they are being serious that it will generate bitcoins that can be used to buy stuff from others.  This thing will make nearly nothing on a daily basis, and probably use more power than it generates in bitcoin by the time it is released.  There is no way anyone can buy one of these and use the profits to buy anything really.

Still very vague. I can't seem to udnerstand how will this facilitate Bitcoin payment integration in websites, as it apparently does. Why should a merchant opt for this instead of BitPay, Electrum payment functionality, just giving out an address, etc?

[LFC_Bitcoin]

It looks awesome, it really does. I don't have any need to own one at the moment though so unfortunately I won't be buying it.

I'm just a HODLER, maybe in the future, it's not the price but I just don't need one.

They don't give enough information to verify their claim that "the 21 Bitcoin Chip has an efficiency of approximately 0.16 Joules per Gigahash and can calculate 50-125 Gigahashes per second."

Will be released just in time for the day after Thxgiving Xmas sales.  Woot.

400 USD is close to 2 BTC. I think, rather than buying this 21 Bitcoin Computer, which seems nothing more than a raspberry miner, with 2 BTC, it is better to buy 2 Ths from www.CloudMining.website. That would be more profitable in my opinion.
