When Microsoft officially launched its cloud-based Power BI analytics service almost a year ago, it cost upwards of $US40 a month. Some 12 months on, a new preview version has just been launched and the price is about to be cut significantly.
The basic price for the full version of Power BI once the preview is over and the new version goes into general release will be $US9.99 a month. Unlike the old version, you won't need an Office 365 Pro Plus account to use it.
If even $10 a month sounds too expensive, there will also be a free version. The main benefits of the paid version is a higher data capacity (10GB/user rather than 1GB/user), live connections to the data services you're analysing, and the ability to schedule hourly data refreshes. With the free version, you can only schedule daily updates.
One annoying restriction with the preview version: you have to have a "US business email account" to use it. International availability is promised for later in the year.
Microsoft has also launched an iPad app to access Power BI, and is promising Android, iPhone and universal Windows apps later this year. Read the announcement post linked below for more details.
