People in the Apple World have been sharing around this link to Robservatory's all in one Apple Watch Spreadsheet. It's a great spreadsheet that goes through all the different models, including prices, sizes, and weights of each individual offering.
The only thing lacking is that the prices are the US prices. And as most Australians know, the US prices are really different from the Australian prices.
So, I've updated Rob's spreadsheet to include the Australian prices. You can download it here. Rob says on his site that it's okay to download and distribute, so I figure that flows to this version of his spreadsheet too.
