As someone with a family who just moved from Windows and lost the Rooms feature I can say FamilyWall has helped a lot. Automate is a nice alternative to Tasker. @Voice is great for reading my .pdf's out loud while I'm driving. ES File Explorer Pro I'm in every day! Zedge & Backgrounds are great for my wallpaper, notification & ringtone need. Dragon Mobile Assistant almost meets my needs for a Cortana on Android. Current Cortana on android is no where near as effective as the Cortana on Windows Phone.
