As for the volume.. well there are so many useless apps that it's next to impossible to find a useful one today. When I look for a programming tutorial app they all are very marginal and I find that using the web directly via say, Google, is still the best way to find out any information.
At this point it might be best for MS to purge all but the "best" apps and start over. That way they can keep track of the new apps this time around. Will it happen.. not likely and that's a shame.
I have checked the Windows Apps Store for free apps that I would find useful. So far I have only found a few that I kept installed. I haven't checked the paid apps so I can't comment on them.
Herein lies the greatest problem for Microsoft....
The have totally redesigned Windows 10 to enhance the Metro Apps, if the apps are really of sub-quality then it renders at least half of Windows 10 functionality as useless, why devote so much time and effort to garbage apps.
and while I agree that Apple and Android have many useless apps, the difference is that sites you may frequent, banks, stores, etc. have their own apps with links directly to those stores for easy install, unfortunately, this has been a dead end street for Microsoft.
Passing fad? Hmm that must be why Microsoft is making billions out of their devices alone. Wake up - smell the coffee!
Oh and please do not get me wrong, I am passionate about computers. I enjoying using them, building and upgrading them and have 5 machines on at the moment around me. I have spent thousands on the machines and software over the last 20 years most of that going to Microsoft for OS, Office and Map Point programs.
Here again is another obstacle that Microsoft has produced for itself. Currently, people have to develop apps for windows 8, 8.1 and now Windows 10, all with different stores. In addition (if not mistaken) Microsoft wants developers to make sure the new apps are portable to the Windows Phone, desktop and tablets. That is a lot of burden to place on developers.
I just can't see a lot of developers ready to jump on that band wagon, unless they are garbage app producers whose apps really don't do anything. IMHO
@ Trust_No1. From the Apps I have seen in the store your last statement may very well be true.
