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!"
@Quikboy this is not true. Narrator isvery basic and highly unusable. Try using it to read a web-page. Voiceover is included in the core of the OS and can even be used to re-install a Mac from scratch. I always need sighted help or have to hit tab+enter millions of times and hope it'll start the Windows setup/install process. I had to spend $1300 for a screen reader under Windows, because Narrator is beyond basic and can't do anything;JAWS or www.satogo.com are both screen readers manufactured by companies which are a million times better.
