Hello MacRumors members, I've created Buynotify, a free universal app that essentially puts the Buyer's Guide in your Pocket. It displays the average lifetime of Apple Products and gives advice on wheter you should buy a new Apple product now or wait a little more. It also features the history of products and the app will send a notification when Apple adds a new product. Also included is a direct link to the Buyer's Guide. It looks like this: You can download Buynotify for free from the App Store I hope you like the app and look forward to your feedback!
