Pulse (I see it on the market, but it won't install on any of the WP's I've had. Lumia 900, HTC Surround, nor 8X)
Works on the Lumia 920. Probably a Nokia WP8 exclusive. I seem to recall having it on my Lumia 800 though I can not be sure.
As for Windows 8, all the reviews Ive read have said its a great OS for tablets and touchbased computers, they love the ModernUI for that, but the UI is that good for desktop computers with a traditional monitor.
Personally I use Win8 on my desktop computer. I dont find the experince far removed from Win7, tbh. You launch desktop and thats where you hang.
This is how Id use it on a touchbased laptop as well; desktop mode for when its used as a laptop, and ModernUI when used as a tablet.
Fairly simple and easy. So personally I dont see why theres all the hate. Theres Modern UI for touch, and desktop-app for people who want a Win7-like interface.
But thats just me.
As for Windows Phone 8, there could be 0 more apps coming to WP8, and Id still consider my 920 one of the best phones Ive had.
This is probably because I never got sucked into the whole app-dependancy. I never got why people needed a facebook app instead of demanding a better browser that runs facebook like you do on your desktop. Like microB. That browser was amazingly awesome. "Its easier to handle". Yeah, 'cause the browser isnt en par with the way you work on your computer.
Meh Im rambling like an old geezer. What Im saying is that I never got into Instagram and using bank apps etcetera, so personally my app dependancy is quite low. Which seems to be a blessing, since people are raging about apps all the time, and I can safely sit in my blissful ignorance and enjoy the integration of social networks with my Me-tile, contacts and media without losing my mind over Instagram.
Though I of course would like to see WP8 recieve great apps of all the things people want on it, Im just really happy Im not lacking any cruicial app myself.
