I'm trying to grok the 12.9 iPad 'for the couch' or 1on1 presentations...
Personally, I think Apple is driving for 3 jobs for it's iOS devices with crossover points
1) on the go portability (one hand) - iphone/ipad mini
2) personal productivity (one person) - ipad mini, ipad air, ipad 13
3) professional productivity (think Doctor, Designer), iPad Air, iPad 13
The Mac Line still does a different job (multi-task professional). It's the 'connection workhorse'
I truly think the appleTV will become effectively a 'server' that an 'app' on an above device will control.
And the TimeCapsule will become 'iCloud Local' controlling local syncing, caching stuff for upstream and downstream. As IPV6 gets onto the Internet backbone... I wouldn't be surprised that Bonjour will be hardened keep your local storage always online.... and allow people to control what they truly put in the cloud, and what they want to access over the internet (Every home is part of the server farm in Apple's Cloud).
All good points.
I did forget to mention iCloud as an integral part of the mix. I also agree, with you TimeCapsule becoming "iCloud Local!" People, by and large, still don't trust the Cloud as the only storage choice for a variety of reasons, reliability,security, etc.
My daughter is a doctor and she swears by her iPad Mini. Fits perfectly into her white coat pocket and at home she is constantly checking on her patients back at the hospital and to answer questions from the nurses and sending quick instructions to the nursing staff. She just loves it. She gave away her full-size iPad to her mother.
It would be great for ATV to be a server, too! :)
