You might remember Chrome to Phone being shown off at Google I/O 2010. When browsing a website on your computer, you can hit “Send to Phone” (in either Chrome or Firefox) to make the page automatically appear in your Android browser, wirelessly — no need to email it to yourself or manually copy the URL.
Likewise, YouTube videos launch in the YouTube application; selected text gets copied to the Android clipboard; selected phone numbers get dialed. Best of all, you can search for Google Maps directions on your computer, and send them to the phone, which will switch to Navigation Mode, ready to go. Try using it to load this page in your phone’s browser; you can then tap any of the QR codes to go straight to that application’s download page.
The ability to click one button, and immediately launch a video, start navigation, or anything else is by itself a reason to buy a phone. Imagine: I’m on the road, needing directions. My roommate can go on my computer, load up the directions on Google Maps, and in one click they’ll pop up on my phone. It’s faster, safer, and awesome. Er.
