There is still so much more to do that won&#x27;t require gargantuan cpu&#x2F;storage&#x2F;io&#x2F;screen&#x2F;etc. resources, that I don&#x27;t think we are in an &quot;end of history&quot; phase yet with the current conceptualization of these devices. Just a few personal itches off the top of my head that have yet to be scratched:<p>* There is still not a good solution for group-transactional data over the devices as a first-class citizen feature in the system. Live, collaborative editing with versioning of just a list, for starters, is considered an app&#x27;able feature worth $50 USD per year per person.
* Internationalization still takes a back seat. Calendar apps still don&#x27;t pick up that if you set an appointment for someone in a different time zone than you, you are likely scheduling to a time convenient for them. There should be an option to auto-detect and display applicable time zones as you create the appointment.
* Customization still takes a back seat. When I add custom phone types (&quot;concall&quot;, &quot;support&quot;, &quot;after-hours support&quot;, etc.), it ends up UNSORTED in the list of custom phone types when I go to choose one. That&#x27;s just the tip of the iceberg of enhancements. For address records of people in a specific organization, I want to be able to set only a certain list of custom phone types for anyone in that organization.
* There still is no sense of tracking versions of information. I have thousands of contacts, and I keep track of old addresses for example; it helps me orient myself to the possible cultures someone has experienced. But only the here-and-now data is recognized.
* Linking data between apps takes an explicit act of coordination between app developers; the Newton data soups were particularly good with breaking down this artificial barrier.
* Deep-linking into your own data from within an app in general is not very well-recognized as a use case. Not to speak of deep-linking from an external laptop.<p>I&#x27;m personally gravitating back towards making my information in my Emacs Org mode buffer the primary system of record, and the phone is just a thinly-sliced perspective of that.
