Interestingly they have an active jobs page, from which we can infer a little about their plans??

The company will probably be a big deal. For one, the investor list is top notch. Additionally, @balajis is a cofounder and c-level exec. For those who don't know him, he was a partner at Andreessen Horowitz (is leaving now that 21.co is coming out of stealth), successful entrepreneur before that, and he also "...obtained BS, MS and PhD degrees in Electrical Engineering and an MS in Chemical Engineering, all from Stanford" (source: http://blog.pmarca.com/2013/12/09/balaji-srinivasan/ ), so he's got the technical chops for this.
He's given a number of interviews over the last couple years, and talks a lot about bitcoin on twitter. One topic I've heard him bring up more than once is the idea of bitcoin enabling machine to machine payments (ie, the gazillion theoretical car-autopays-the-meter use-cases). So I think there's a decent chance 21 is working on an embeddable-in-anything low-power bitcoin-wallet-on-a-chip.
Cheers for the info Mel - could be really great for our BTC community, I'm looking forward for future announcements from this group
Likewise.
Another point... 21 is *bitcoin* focused. Not "cryptocurrency"....*bitcoin*. Think about the network-effect depth that widely distributed bitcoin-only hardware will bring.
