Well obviously I can't speak for wp8 but the likes of whatsapp never really worked, never received notifications for anything other than email and sms.
Dolphin browser (internet) Engadget, facebook, twitter, Economist, BBC news, Sky sports football, ESPN cricinfo, Unified remote (control PC from phone) Nike + Running, Google maps (GPS navigation).
Which apps do you use most?
What's missing Mike?
I'm interested as I'm considering going from Droid to WP8.
I know the economist is missing but that's about it.
Games would be nice, but then again most touch controlled games I've tried are shit. Only puzzle and RTS games work and their is a serious lack of decent RTS games on android anyway.
Run keeper is terrible, there's no Swype. The games they do have are pretty poor even by phone standards not to mention overpriced. The Xbox interface is two to three extra layers anytime you want to load a game.
Nokia drive is fantastic I must admit but outside that literally every app is better on ios or android even if there is an equivalent on wp. Media has to go through zune.
Podcast management has to be done through zune.
And finally: no eg app.
