Food delivered to your gate at the touch of a screen? It sounds too good to be true, but it's happening at a handful or airports.

About 7,000 Apple iPads are being installed at La Guardia Airport in New York, Toronto Pearson International in Ontario and Minneapolis-St. Paul International in the Twin Cities in a collaboration between airport food and beverage provider OTG Management and Delta Air Lines.

In the Delta terminal at Minneapolis-St. Paul, iPads at seats in the gate areas will give airline customers up-to-the-minute flight updates, as well as free access to the Internet. Plus, fliers waiting for their flights can order food from a selection of new restaurants in the terminal and have it delivered to the gate.

"If I'm going to spend $10 on a beer, I'd rather do it on an iPad," said Michael Card, who was traveling recently through Minneapolis-St. Paul, "because it's more fun, more exciting."
