Got a Vista laptop and a Windows Mobile Smartphone? If so, then you already have a way to control PowerPoint with your phone – all you need is some SideShow software. To get started, you must first pair your phone with your laptop via Bluetooth (if you haven’t already done so), then download SideShow for Mobile. SideShow for Mobile is an application for Windows Mobile smartphones (versions 5 and 6) and PocketPCs that let you use your phone as a Bluetooth SideShow device. The final step is to download the Office PowerPoint Remote gadget. With this gadget installed, you can control PowerPoint with your phone - no remote required! You can move forward and back, jump to a specific slide in the presentation, preview the next slide, and view the slide speaker notes on your device. It will even work right from the Today screen so you can just use the hardware buttons on the phone to control the presentation. Nice!
