Proud to be a Datanaut!
Thanks very much, appreciate that, but do these relate to the old version of Power BI before the new release of BI which was I believe only a few days ago, on 24th July?
I've had a look and it appears they do?
Given the date of most of the reports and the fact that many of them refer to Power BI for Office 365, or simply Microsoft BI; I'd suggest that they're either referring to Power BI 1.0 or bundling everything together in a high level overview which, when you see what they're comparing them against, is perhaps a bit silly.
I think it might be a short while before such analysis and research companies do any real comparison with Power BI (2.0)
