Sorry if you took offence at my 'assumption' - it wasn't intended at you directly but at the world in general!
I am also sorry that your Macs didn't work out the box - I must have been one lucky person - my IIci, Quadra 700, 8500 and original (non intel) dual G5 always worked fine, out of the box and years later. my Mac Book Pro and iMac, touch wood too.
And yes, having gone back to the link you posted, right at the very bottom of the page it does say it's in Beta. But here is my issue with this - and it just shows a move to 'sharp advertising' not something Apple has been known for since Gil Amelio was ousted.
It would be more appropriate, and common practice, if there is a claus to something to put an asterisk in the title headline, i.e. indicating there is something to read at the bottom of the page. Even, TV adverts have that.
So then, my critisism for Apple is - where is the direct support with work-a-rounds.
Your analogies of buying a house and car - OMG - are you kidding - cars cannot be released with anything in 'beta' - anything found not meeting design as advertised or required by law are immediately recalled.
Same thing goes for a house. I am not declaring the iPhone 4s a BUST - and of course we need to give Apple a chance to rectify - BUT the difference is, I don't see any support as yet and this IS a feature we have paid for - or is it free???? and if it is free why was the app removed from the Apps store and why not available on other iPhones?
I think you are missing the point - and my 'frustration' - if you are going to 'go-live' with something still in Beta (but kinda hide that) but make it a huge selling point to upgrade, then at least put in place a more appropropriate support process. That is all. I hope this is not going to be a change in Apple's philosophy moving forward i.e. releasing USPs to the market early when they are not ready - I am sure I am not the only person who has had their apple products work out of the box as advertised, in the past - This, in itself, has been one of the two (the other being ease of use) main USPs for Apple since the early days.
In the meantime - we will continue to rely on the many user communities for support - WHICH in itself could cause more issues for Apple. Just poor Release Management.
