Mobile Technology in a Seafood Restaurant

Good day, fellow PalmAddicts readers. The other day I went to a seafood restaurant near my house. It has operated for several months already, maybe even almost a year now, but I did not visit it until that day. The food was fine, not too excellent but not too bad either, and the price was not exorbitant. But I was particularly impressed by something else when I was there. I noticed that the waiters and waitresses all each carry a PDA around, and they took orders from the customers with it. I said impressive, because although it may not be too big a deal but it is also not something you use to see any day in a restaurant in Indonesia. Apparently the menu list had been loaded to the PDA, and the waiter/waitress just needed to tick the menu (checkboxes, I assumed) and enter the quantity. The orders got transferred right away to monitors in the kitchen where the kitchen staff would then read the orders and started cooking the dishes. This eliminates chances of wrong orders, I think. After the orders were ready, a printer terminal would produce the order print-out so that the waiter/waitress could take it and place it in the customer's table. Very neat overall. I did not manage to catch the brand of the PDA used, but I noticed that:
(1). It was black and looked quite slick.
(2). It was definitely smaller and slimmer than my O2 Xda IIi PDA Phone, small enough to be put into side pocket, but still bigger than O2 Xda Atom.
(3). The waiter/waitress used stylus, not QWERTY keyboard.
(4). It was most likely just a PDA, not a PDA Phone.
(5). There seemed to be no camera. Now that is what I call taking mobile technology right into workplace. Maybe next time I visit that restaurant, I'll brace myself to ask the brand of the PDA.
