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 love the idea of being able to try out new ideas/mixes on the go because I travel a lot but there are a few things which mean I'm not going to get this. The real deal breaker is the lack of stereo cue support, mixing on this thing is gonna be fiddly enough as it is without having to change whats coming out my headphones all the time! Especially if you DJ a style without very clear beats/cue points like jungle or dubstep lol also I dont like that you can only EQ one channel at a time, no quick switches of the bass back and forth. It has no line in for recording and £500 is waaay more than I'd be willing to spend on what is essentially a gimmick. If I had £500 to splash on new DJ gear I'd be getting a second pioneer cdj800.
