Let the hive mind of Engadget get that for you.
"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 would definitely get one if they can get the pictures to look better. I'd rather get a $350 decent panoramic camera than waste my money on a $150 toy. If the trade off for the convenience of a getting a quick 360 picture is grainy pictures and blurry images, I'd rather spend $50 on panoramic software and use my 7 megapixel the old fashion way, or get a mirror attachment. If you are going to take a 360 picture of your recent European tour, at least do it right, or at least decently. Please improve the pictures, and I would buy one!
