Presentation Mouse
This may be a little geeky, but I came across a new gadget that you might like to take a look at. It's a nifty little mouse that doubles as a presentation remote control. It enables you to easily step through slides etc. Allowing you to maintain delivery without worrying about hitting keys on the laptop everytime you need to move slides. But....it also has a laser pointer built in - the ultimate in geek chic? I can see the sales and marketing guys loving that. This aside it's a really neat device that could be really useful if you deliver a lot of presentations. Check it out at the following link:
