What happens for SMBs when touch screen technology and VoIP collide?

Last month Nadeem Unuth posed the question: "are touch screens better for VoIP?" The central argument was that VoIP is closer to natural language and freer from the restriction of digits. Totally agreed. VoIP lends itself to a techie and glorious level of openness, with apps like fring®. VoIP is making smart phones even smarter. Why does anyone need to be tethered to desks or computers anymore?
Touch screens are here to stay simply because they are an appealing and useful innovation - but touch screens for the sake of it can be expensive and pointless for SMBs.

POI terminals cannot replace the value of being greeted by a real person, but they can provide basic information to people in search of help. The hospitality industry has widely adopted touch screens and for good reason. But I wonder, does the waiter or waitress at my local diner really need to save the extra ten seconds by entering an order on a networked tablet table-side? If his or her short-hand is no good, than maybe it will save about 15 seconds... When employing touch screen technology, companies need to get over the cool factor of being an early adopter and think of the business benefits. The business benefits of VoIP are clear, and they will still be there when touch screen adoption grows and interfaces improve.
I actually do agree with Nadeem about the possibilities of VoIP and touch technology, it just makes sense. Why not take that extra step and combine VoIP with touch screen technology?

I can easily picture a scenario where the waiter or waitress also need to answer calls for the Manager who had to step out. The manager can set up a hunt group from his/her hand-held tablet and feel sure that they won't miss that call for a reservation from Mayor Bloomberg's people or perhaps... Beyonce?
