I guess you might want to ask yourself why you would want a standalone calculator in 2013. But when it looks as good as the Braun BNE001 ET66 calculator, it's hard to argue against.
This is a classic 1987 design, the work of influential designer Dieter Rams (in association with Dietrich Lubs) and the inspiration behind the original iPhone calculator app. It's said to be the pinnacle of Rams' principle of minimal modernism.
The reissue if a faithful reproduction of the original and should be around in the coming months. Although right now, we're still to hear exactly when or indeed, the price likely to be asked. When we get wind of either, we'll let you know.
