GMate’s Yopy is a Linux-based handheld, which we first looked at in October last year. At that time we reviewed a version of the device that had to be bought from France. Now, two models are available direct from the UK. We looked at the less expensive device, the YP3500; the other, the YP3700, has a CompactFlash slot and costs £360 (inc. VAT). There are some significant differences between the Yopy of today and the model we first looked at.
