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've had one for a few months, running XP (mine doesn't have the ears) and my biggest complaint (like others) has been the keyboard. It was very popular while abroad. I guess it's not available in parts of Europe yet.
However, a friend decide to test the fingerprint sensor.. AND IT LET HIM IN. Not consistently, but more than once. This was a bit distressing.
I haven't tried swapping any keys yet, I much rather go for (unlikely to Ever happen) a full replacement. Dedicated arrow keys alone would make this thing more usable.
