Techdigest asks whether the Leon Roswell is “the most purdy calculator yet“. I rarely use a proper calculator these days (not least because Google Calculator is just so useful, especially converting units) but this one does have its charms. It certainly has got craft going for it – the body is made out of just a single piece of aluminium with some laser cleverness, which is admirable. It also does currency conversions (although it doesn’t say how it updates the exchange rates – presumably you have to tell it what they are)

To answer the questions, yes it is purdy, but overall it left me feeling a little cold – perfect for an ultra-minimal office with big skylights and brushed metal finishes – but no-one I know in the real world ever keeps their office or desk that tidy for more than a nanosecond. Technology should be more welcoming and realistic – a battered ten-year-old Casio has a lot more charm and appeal – this calculator, you fear, would be the type to insist you perform only complicated and intellectually stimulating calculations rather than just 2+2.
