I have saved up my gift certificates to Amazon and now I can buy either a Mighty Mouse or an iPod shuffle. Neither is a critically needed purchase but I still cannot decide. Mighty Mouse--always been curious about this product and wonder if I could use it as a wireless remote of sorts for advancing powerpoint slides (is that possible?). I use a laptop so a bluetooth mouse would be nice and I have been waiting ages to get it. Shuffle--my 3G iPod is showing its wear. Granted for the car I can still plug it into the charger and I am not really using my iPod outside of my car any more so maybe it is not really needed. Then again, they look pretty tempting Does anyone know if the Mighty Mouse could be used to advance powerpoint slides (within a reasonable range)? Thanks!
