Without more information, it's hard to say what the best route is. Will you just be watering your house, or do expect to water your yard and garden? What's the quality of the city water, compared to well water in your area? How much will the hookup charge be? What would your monthly bill be? How reliable is the power in your area? (losing power is a nuisance, but losing power and water is serious aggravation) As someone else said, you also need to know what the pressure is at the main; that will tell you if you can stand much pressure drop. That all said, I don't think you will be happy running a one inch line over 2000 feet. I'll bet the water main is much bigger than inch and a half. 12 inch is pretty typical. I'd figure on running at least two inch pipe, unless the pressure at the main is really high (like 125 psi). (You don't need to have a 2 inch tap on the main, just get a one inch tap and connect it to two inch line on your side of the meter.) Remember, pressure drop is proportional to pipe length and inversely proportional to pipe cross sectional area; 2000 feet of 2 inch pipe will have as much pressure drop as 500 feet of 1 inch pipe. 500 feet of 1 inch pipe is about the same as 125 feet of half-inch pipe, but you don't see many people running half-inch house mains, do you? There's a lot to be said for having your own well: It will be cheaper in the long run, particularly if you do much yard watering. On the other hand, a well is definitely much more aggravation than municipal water.
