Overall the look and feel of the app is similar to the desktop version, interactions are reasonably snappy, but there are a few very simple roadblocks towards making this a credible alternative to the desktop version. I did not bother to go into a more detailed review at this stage:
- Fonts. If you used custom fonts in a presentation designed on your desktop, they will not show up in the web app (I use a Mac so I cannot embed fonts inside a PowerPoint file). This is a showstopper: it is very difficult to edit a presentation when you cannot see what you are doing, and completely kills the option of using the browser to present your slides.
- Data chart. You cannot edit or create them. No use for a business presentation.
