I understand MS view about this and in the long run it should be better.
Back in 8, apps like Calculator, Alarms and Clock, Xbox Music, Games and the Store were all attached to the OS itself.
Since these apps were part of the OS, launching the apps took an instant to open.
This also meant that updating the apps would have to go with major OS updates. This made progress for these apps really slow and was one of the reasons why these apps were behind in features.
With Windows 10 however, they're now real apps that can be updated in the Store. That is why we now get regular updates which is a good thing because MS will be able to update apps individually without an OS update.
We should then hope that MS can iron these apps out to where it can be similar to the Calendar app in 8.1
It has a splash screen but it's really quick so we don't really complain about it.
I truly understand what you say. But, can you tell me how many updates did the Calculator or Voice recorder or Alarms app got? I
don't think these apps
should need updates frequently. MS is a big company and can make these apps the greatest for once and can bake in the OS.
Also, the Photos app, tell me you guys, what better functionality the WM10 app gives us, that was not available for us in 8.1 app? Can you move or copy photos around from a folder to another? No! Instead, it's more difficult to reach to folders in the new app.
'Albums' is a nice addition, but my phone app never creates auto albums while the PC app does. And I would more likely arrange photos in a folders than manually creating albums within the app.
Save the lags, bugs and crashes, there is no any improvement over the 8.1 app, despite being an app, having the luxury to update anytime.
Same goes for Groove music and Movies & TV apps. Sure, those who use or rather can use the Groove music pass or buy from the MS video store would welcome the updates. Folks like me, who live in a country, where there is no Groove music subscription or MS video store, no unlimited Internet plans, no readily available and free WiFi, miserable data speeds, we like to keep our content locally on SD cards. And for that purpose, the Music app in WP8 was way better than Groove music. Sure, the video player could be improved. But I don't think I need updates every week for local playback.
If any app which should have been an app is the File Explorer. It doesn't yet have ZIP support which is crucial in my opinion.
Windows 10 Mobile is just not optimized. Microsoft should start optimizing it.
