Haha, went from the first few pages, several mentions of "No service, must be AT&T", to this page, and of course "No service, must be O2"
Agreed though, O2 coverage is hopeless.
If it comes without a contract I'll probably just use one of 3's new Mobile-signal-to-wifi thingies which I bought recently and have it connect to that. Whilst their customer service is rock-bottom (is there such a thing as a decent mobile phone provider?) their 3G coverage is practically everywhere.
Can't see why this'd be a "controlled leak" a) they generally mean information with regard to controlled leaks, not pictures. It's useful for people to know a tablet is forthcoming and get excited about it, but the keynote will have more of an impact if people haven't seen pics of the device and b) Why would they leak something the day before the keynote, it makes zero sense to me.
It makes sense for it to be an iPhone type OS, as that's very much been their baby as of recently, it's designed from the ground up for touchscreens, more suitable for low power/high battery life applications, and of course Apple have great control over it and over the distribution of third party software (and the associated profit share!). It wouldn't make any sense from their perspective to give it the full OS X. Besides I think their eventual goal is that having one big computer sat on a desktop with a "classic" desktop operating system will go the way of the dinosaur.
Going to be very tempted but it depends on a lot of factors - what it's like obviously, whether they've put any thought into it (and the adaptation of the iPhone OS) or just created a big iPhone, price, and whether I get my iMac back from repair before the next Christmas comes along.
