The count of apps available in M$’s app-store for “8” has reached 42K but the rate of new arrivals is a tiny fraction of the first few months… They were getting ~500 new apps per day. Now it’s just a bit over 100. That’s death for a “platform”, eh?

Put it this way. Debian GNU/Linux has about that many packages and many of them are wonderful applications for clients or servers so “8” may have “enough” to do something but combined with lacklustre sales to consumers it looks as if developers don’t want to make the effort if the consumers don’t buy it. Makes sense. Small user-base means no payoff for developers paid by the app. Compare that with Android/Linux which has hundreds of thousands of apps both $free and $non-free.
