Each year we celebrate the very best products in each category in our TrustedReviews awards. If you've not checked out this year's results, do so now.
However, this 'best of' round-up is a little different. We're going to look at the products that are important in another sense.
These gadgets mark a change, either for the market, or for the company making them. And some of them will be product remembered for years and years to come.
There are no real winners here, but if you want to know which products are the sign of things to come then you've come to the right place.
And if you think we've missed any, feel free to let us know (politely) in the comments.
