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'd be happy to run the free java Opera Mini on the phone. I'm not a fan of the iPhone's two handed browsing, I'd rather have a browser that reformats everything into a single column so I just have to scroll down.
On the other hand, I just learned that only one iPhone application can run at a time, and third-party applications never run in the background. If users switch to another application, answer the phone, or check their email, the application they were using quits. ( http://www.techcrunch.com/2008/03/07/iphone-sdk-some-of-the-details-arent-great/ ) So I'm a lot less jazzed now about third party apps on the iPhone.
