We've seen concept videos for apps that let us try on watches, but now we've finally got something we can actually play with. Now we can try on watches without ever having to put on pants and leave the house.
This would have been great when I was buying glasses today. Switching back and forth using this would be much easier than removing and putting on the same few pair of glasses.
More importantly, the pair I ultimately went with I ordered in a color that wasn't in stock, so I hope they look as good as I think they will.
