In addition to seating 4 (or more), islands today are used to house "luxury" appliances that do not fit in the cabinet structure like a second microwave, second oven, wine refrigerator or even another cooktop. Islands many times are fully wired for electricity and have plumbing for a second sink. The base of an island can be used as a wine rack. The possibilities are almost endless.
A kitchen island is not a new concept, since they were known back in the medieval days when knights were bold. They are assuming increasing popularity in today's kitchens, particularly in larger homes where the kitchen is more than just a small cooking area compressed into an area somewhere between the dining room and the garden shed!
Space and Design are Important : You need around 3 feet of walking space around the island unit, and you must be sure that the drawers and doors in the cabinets have room to open. If you keep to the 36 inches then you should be OK. The only dimension that must be stated is that of the counter height. Ideally it should be the same as the rest of your kitchen units. If not, then it is not a disaster, but can be disconcerting when you are working on the various surfaces at varying heights.
Checklist : Keeping a checklist can be very helpful when it comes to having lots and lots of things to order and purchase. It will allow you to keep track of what has been purchased and what are the outstanding items that need to be ordered. Always keep the checklist handy as you will never know when you will need it for reference when you are out at the mall.
