"We need a digital camera that can be switched on and fire off that first shot fast. It's not a commonly tracked statistic on any review site, and nobody seems to have this information for every camera. We were hoping other readers could inform us as to what small digital cameras can fire off their first pics in under a second (ideally under half a second). It needs to be small, but mostly, just really quick in operation. Thanks!"
I use a normal $200 garmin car version on my GIXXER, why should motorcyclists take it in the back door for a 300% price increase on a GPS unit? I am still waiting to hear why these so called "two wheel" versions should cost so much more than their "four wheel" equivalents?
