The Slim features built-in WiFi (no cables for using the Internet!) while the Elite and the Arcade have no WiFi.Here are the differences between the two: The Xbox 360 Slim replaced the Elite line. Costing only one hundred dollars more than little brother Premium, the Elite comes with a $150 hard drive, making this a $50 savings. At $299 dollars, it is the most pricey of the available models, but still a great value. Your 360 can fill up fast, and with this roomy bad boy, you'll never have to delete anything ever again. The Xbox 360 Elite comes packed with a 120 GB hard drive. Know what you are buying to avoid machines with faulty motherboards. The 360 Pro edition is split between three different hardware models. Note: Even among original Pro or Premium systems, there are divisions. However, if you're like me and can't stop buying new songs for Rock Band and hate to delete even the worst demo, you might still be filling that up as well. In my experience, 60 GB of space is enough for all but the most prolific packrat.If you've paid for a game, you can re-download it at no cost. However, it is possible that the smaller drive will delete some demos or titles you've already purchased. 20 GB is relatively small, but for most purposes it is adequate.This is a good compromise if you want to pay an Xbox Arcade price for Elite performance. These are old (read: used) Premium models that have had their innards replaced with less failure-prone hardware.

Pro/Premium models that are for sale new are usually refurbished.Pro comes with either 20 or 60 GB, while Premium only comes with 20 GB. The original 360 model includes a 20 or 60 GB hard drive which allows you to download games, movies, music, demos, and downloadable content for titles like Rock Band.
