Fewer choices = worse
Pretending that having fewer apps available is an OK thing reminds me of using a Mac in the 1990's, when nearly everything appeared on Windows first, and on Macs a few years later, or never. It was not enjoyable.
If WP market share remains in the single digits, the bulk of the apps, whether treasures or turds, will never get ported. For business users, the good news is MS will undoubtedly make the WP Office apps more polished than the versions for the other two platforms. Plus, there will likely be some form of emulator (maybe there is already), like BlueStacks for WP that will allow Android apps to run directly (as BlackBerry now does). Also, MS isn't going to just walk away from WP. Maybe. Then again, with all the weeping and wailing, maybe their fragile emotional states aren't to be trusted.
