When we ask readers like you to help us rank the top gadgets, we usually focus on the best (and sometimes the worst). Recently, you selected our Readers' Choice winners for the 2013 Engadget Awards, but in the spirit of our 10th birthday, we wanted to try something a little different.

Do you have a gadget that's changed your life? Perhaps you made a leap from the LG enV VX9900 feature phone to the mystifying world of smartphones and scooped up an iPhone 3GS (like this author did in 2009). Or when you decided to move to the other side of the world and your Mom bought a Logitech QuickCam Pro 9000 to keep in touch and see your darling face over Skype.

Whatever it was, we want to know what gadget it was for you. It can be as simple as the gadget that made your everyday routine better or something a little more sentimental. In the form below, please try to use the proper name of the gadget and the version (for example, "Kindle DX" tells us more than simply "Kindle"). If you'd like, share with us why you chose this gadget and your Twitter handle.

In about two weeks, we'll sort through the results out and showcase five of the most life-changing gadgets from the last 10 years. (If you have a picture of this gadget, share it on Twitter or Instagram, tagged #Engadget10 -- we'll be posting some of our favorites.)
