It's heartshaped and adorned with Swarovski crystals, leaving us in little doubt about the marketing plans for this surprisingly practical gift. Of course, you could preload the 1GB flash memory (the heart comes apart to reveal the USB port) with pictures so she can keep you close at all times. £105 inc VAT from www.swarovksi.com.

This is just one of the products in our Valentine's gift feature.
