Today Microsoft announced the availability of Power BI preview also outside United States.
One important thing to note is that also the mobile app for iPad and iPhone are also available worldwide. Jus go in the Power BI Download page and select the app you want. For a PC, I strongly suggest to download the Power BI Designer. You will find another good reason to do that later this week on this blog… but no spoilers by now!
I suggest you to read the longest recap made by Chris Webb on his blog: there is also some news about public preview of Office 2016.
