Sorry Steve, but this article is yet another attempt to justify Symbian's shortcomings and present them as advantage of some kind.
You say that app-integrated update might be a good thing and give 2 advantages:
1. the user doesn't have to lift a finger
Your example would mean that you start an app, intending to use it, instead your workflow gets interrupted by update process - restart of app etc.
For me, true definition of 'doesn't have to lift a finger' approach is system as implemented in Android 2.2 at the moment, when you check whether app should be able to update automatically and from that point on, you don't do a damn thing. It's always up to date. Even better would be if this option were on by default (on wifi), so mainstream users would have apps always updated. IF (stressing IF) you feel the need, you might install latest alpha/beta as apk package file, same as in Symbian.
Iphone OS is close, but doesn't have the automatic update capability as far as I know...
2. updates obtained from the developer's server will be bang up to date
True, but there are two major problems with this:
1) You might not always want to go for the latest, greatest alpha version available. With Gravity, this works because janole is such a great developer, but even with him there were several times when one update was following the other, fixing something broke in the previous alpha.
2) How do you get the information? Certainly, you can follow social media channel - twitter etc. of the developer. But honestly, regular Joe the user doesn't even perhaps know what twitter is, and surely you cannot expect mainstream users to follow app developers for such simple task of keeping apps updated.
I have some 70 apps installed on my phone at the moment, following just 2 or 3 devs. For entirely different reasons than updates 😊
I can see the approach perhaps working for you, since you're interested in Telco, but for normal users this is simply too complicated, time consuming and awkward to use.
I didn't write this to do some Symbian trolling that's so popular nowadays, but in hopes that Symbian folks will stop whitewashing Symbian's faults and try to push it to reach level of other modern mobile OS.
