Grateful the UpToDate made it to the platform which is great. it is well done too. Epocrates, Sanford Guide did make it to IOS and android. When will they get to Windows Phone 8? This platform is perfect for those apps.
I don't think I'd use them on my phone since I have access to all that stuff on our computers, but the more apps the better (for the ecosystem health).
In the wake of ACA, baby boomers retiring and millions of NP's out there this platform needs Epocrates and the Sanford Guide. Its time those two organizations stepped up to this platform.
