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 visited an AT&T store and played with an iPhone for about 20 minutes. Sure, it's nice, but...it's overrated. Without being cynical, it's basically a very well made toy. What other device takes you straight to You-Tube? It's probably the most ergonomically portable device that lets you browse the real, unabridged internet. But I don't know where/when I'd use it. It doesn't solve a problem. Actually, I do want one - I just can't justify the expense. It makes more sense to own a blackberry or Nokia N800, or one of those new superthin Samsung cell phones. Or a UMPC. A tactile keyboard would be better, as everyone knows. I can't imagine getting any real work done that requires real typing. Fingerprints weren't really an issue, so that's an overblown problem. Vaguely sliding the fingers to do this and that is better, in a way, than the need to hit a particular key.
The thrill of it wore off quickly, as I stood there playing with the fully functional sample - so now I can get back to my life. If you have an iPhone, I trust your lives are better for it. But I'm happy without one (at least until the price drops to $100 and there's no monthly fee.)
