One of the big questions hanging over Apple's iCloud effort is whether the company can improve on its poor execution with prior Internet services like MobileMe. Lots of iCloud services sound great but how well will they scale as millions of users sign up?
Today came reports that the iPhone's best new "in the cloud" feature, automated assistant Siri, was offline. I just tried to show it off for my brother who's visiting and got "try again later." Not quite the impressive effect I was going for.
