If I recall correctly, 0800 numbers used to be free on mobiles until the early 2000's when somebody came up with the idea of vastly undercutting mobile rates by hosting a proxy phone service on an 0800 number (basically the user dials an 0800 number, then dials the actual number they want and the proxy service uses the tones to forward you on). I used one for a while, paying the proxy provider a bit more than landline rates and not paying a penny in call charges to my mobile operator.

So all the mobile operators slapped charges on 0800 numbers to kill the practice, which was understandable at the time, but now with VoIP etc. there's easier ways to avoid call charges and anyone on a contract gets free minutes by the bucketload anyway, so I doubt we'd see the return of these services if 0800s were made free on mobiles again. Now it's just a case of not wanting to relinquish a nice little earner...

Why this form factor?

Have I missed something? I've never seen what the benefit of a 7-8 inch tab is. I love my Galaxy Note, but that's pushing the upper limits of what can be considered 'pocket friendly' (unless combat pants are making a comeback) so I'm not sure what the benefit of them is over a bigger tablet? Except perhaps being cheaper, but cheap has never been part of Apple's gameplan...
