Your conference room may be outfitted for making top-notch presentations, but how about your briefcase? These days, neither customers nor investors have patience for subpar slide shows. Here are four tools that will help you make stellar presentations anywhere you go.

You can present wirelessly from a laptop, iPhone, iPad, or Android device over a Wi-Fi network using Epson's iProjection app. Cost: $700
