Like many of you, I've been watching coverage of Steve Jobs Macworld keynote (just finished, it had been going two hours as I write this) - he's just formally announced the iPhone (smartphone), running Mac OS X, only one hardware button and with a fingers-only touch interface. A competitor to Symbian OS/S60/UIQ? Not due in Europe for almost a year... Battery life claimed at 5 hours talk time. My initial impressions are that it's a bit of a premium device, with that large and fragile touch screen (which will be hard to read in sunlight etc.)
I can't really see it selling in high street shops, at least not in Europe. $500 in the USA will probably mean £500 over here, and it's not 3G either.
Cool design generally though, and ten out of ten for ambition. Now let's see how far S60 and UIQ can go in the coming year before the iPhone appears 8-)
