This made me wonder: if someone asked YOU what product you would nominate for 'product of the year' what would you say? Feel free to nominate any kind of product and tell us why it is worthy of nomination in a comment.
You don't have to stick to products that came out this year - it's YOUR product of YOUR year, so it's fine to nominate a product that has been available for ages, as long as you have discovered it during YOUR last year.
What would be YOUR 'product of the year'?
