Almost there
- Ease of use. Most people have experience working with Excel. If you know how to create pivots, you can use Power BI.
- Data extraction and transformation (ETL). ETL is a joy with Power Query. It is intuitive, simple and a magical experience to transform poor data into something useful.
- Visuals. Power BI is beautiful to behold, especially Power View.
- Maps. The interactive maps are great built-in tools.
- Cost You cannot find anything cheaper than Power BI, unless you want to give it to every user in your company.
Cons
- Automatic updates. A choice of a daily or weekly refresh is too slow for this era of real-time updates.
- Speed. It takes a while to load all the data into memory. Data with more than one million records will take a few minutes to refresh. Once it is loaded, it starts being fairly fast.
- Changing queries in Power Query. Although Microsoft is working on it, when you delete a step in Power Query, you might have to rebuild your data model. This defeats the purpose of having a fantastic user interface, in which it is simple to change queries.
