I got kinda bored one day about a month ago and I wanted to make a spreadsheet. I came up with a Mac Depreciation Guide. Here's some info on it: The values are from Mac2Sell.net. The prices are from Mac Tracker. If you'd like me to modify, add, or subtract anything, please, do suggest it. The spreadsheet is in .numbers format. There is the .numbers for those of you with iWork. There's .pdf for everyone else. I will make a new post to attach the new files and images. Thanks for your interest! PS: Check later posts for info on the redesign. October 4, '09: Updates. Nothing exciting. Attachments below are for October '09. I'm thinking about making a MS Access database of this stuff... But I've got to learn Access first. October 5, 2009: The attachments didn't upload, apparently. I'm putting a link here in a bit. Ok, a link isn't going to happen, so just go to page 3 for the latest.
