Featured Tech Question: Gotta Have It Gadget

What is the last gadget you purchased? Why did you have to have it?

I purchased the iPhone and converted from my Treo. The iPhone is amazing and is a gadget that will forever change the mobile experience. I haven't played with all of the apps yet, so any app recommendations would be appreciated. One app that my brother uses is Shazam, where you can have your iPhone listen to the music being played on the radio (or on the background) and it will identify the song & provide a click to purchase. So cool. The keyboard isn't great and slows down your email productivity, but the positives completely outweigh the negatives. I am still learning new reasons to love it!
