Despite the deeply intrenched techie community within coffee shops around the globe, the process of buying coffee has yet to see significant innovation. Sure, there are some new ways to order coffee, even via text message, but a unique and elegant purchasing solution has evaded coffee shops and other frequented business - that is, perhaps, until now.

Of all the technologies powering the social Web, few are as under-appreciated as the espresso machine.

We go gaga over great mashups, we drool over high-powered hardware, and we lust for private beta invitations to Google's latest whatever-the-hell-it-is. But none of these would be possible without machines to blast steam through finely ground coffee beans, and baristas with the skill to pull a perfect espresso shot.

Starbucks just launched two iPhone apps. One app, myStarbucks, allows users to find stores, build drinks, and browse the coffee chain's menu and find nutritional information. While this is interesting, the second app is far more exciting. Starbucks Card Mobile gives users a virtual Starbucks Card and in 16 select stores in Silicon Valley and Seattle, users will be able to use this app to pay for their drinks. The app will display a barcode that the baristas at these stores will be able to scan.
