Smartphone UI Stencils may be more useful for professionals in the business of developing iPhone, Android and Windows 7 apps, but I think there's a market for them within the general population.
These thin stainless steel cutouts are made on a slightly larger scale compared to the actual size of the cellphones they represent, allowing creatives to formulate big ideas for the ease of experimentation. To help the drafter out, the brand also has a line of notepads that are magnified paper replicas of the various mobile phone frames. Including everything from the "select," "back" and "options" buttons, the simplified handset stationery provides the perfect palette for formulating the next hot app.
Smartphone UI Stencils come complete with a range of icons corresponding to each operating system and software. I may not be a developer, but I'm sure I could still have a lot of fun with these!
