Since the arrival of my HTC Desire, I have been busying myself browsing and installing apps from the Marketplace. I have come across a small yet useful little app called LinkPush. This app works in combination with the Chrome browser on your PC and Android. When you install the app to your phone you will also need to install a plugin button onto your Chrome browser.
Once installed it will allow you to send any webpage that you are currently browsing on the PC to your Android. Just push the Android button on Chrome and off it sends.
One use is when you are looking for a location on GoogleMaps. Once you have the location you can send it to your Android for later reference.
I am in the midst of moving offices and am currently at the renovation phase. I have been looking at colour palletes online for decoration and painting. So I find it useful when I find something I like I can push it to my Android to show my contractor later
Try out LinkPush and see what other uses you can come up with.
