Looks like Nokia Lumia phones might end up getting proper enterprise support through Good Technology soon (as in April/May). That will probably help change WP market prospects at least a little given that our OS already has Office Mobile, Exchange/Office 365, SharePoint all native, and of course SkyDrive & Lync apps on top.
I'm sure with the enterprise solution we'll see the black Nokia Lumia 800s and 900s (or even penta-band 710s) attract the attention from many professionals. This is a subtle yet potentially very lucrative push by Nokia, it can make a difference especially when Windows 8 tablets start rolling in and Apollo launches.
Also, to be honest, I don't think the app situation is even that bad. I looked at a bunch of "top iPhone app" lists over the past 2-years, it doesn't really seem as if WP is behind enough to give a regular user pain. The current crop of apps include:
Facebook
Netflix,
WhatsApp,
IM+,
Shazam,
Amazon Kindle,
Vevo,
FourSquare,
Flixster,
Twitter
Vimeo
Daily Motion
Fox News
RunKeeper
EBay
Dictionary.com
Some very good 3rd party alternatives like
YouTube Pro,
Carbon,
4th & Mayor,
BBC News Mobile.
Not a bad gaming portfolio either:
Angry Birds (sadly without additions)
Plants vs. Zombies
Fruit Ninja
Parachute Panic
Doodle Jump
+
The Harvest
Tentacles
Kinectimals
Can't forget the Nokia goodies either (though limited in availability):
Drive
Maps
TuneIn Radio
CNN
ESPN
WRC Live
...and the crop coming soon:
Nokia Transport
Nokia Reading
Nokia exclusive EA titles
Skype
Photosynth
Just to add, the ones I really like in addition to the above:
FlashVideo for WP7 (you can play PutLocker, VideoBB, Videozer, etc links on your phone)
Nextgen Reader
My Encyclopedia
IN+ Networking (for LinkedIn)
Armed
Bouncy Mouse
Blue Tomato
Word Arena
Our app situation isn't bad, and it's borderline good IMO, to say the least...of course serious improvements are needed, especially with Angry Birds.
The only people I can see upset at the lack of a couple very specific apps are those who are just too tied into their eco-systems, it's like telling a WP user who absolutely adores their Live Tiles to go and adopt iOS as it is now. Heck they won't even pick up Tango as their sole phone.
