Last year Microsoft released the photo organizer codename Max, based on WPF (a.k.a WinFX). Today there is an update and it requires .NET 3.0, which is installed automatically when you install Max.
The current beta release, includes the Photo organizer and also a Feed aggregator. The aggregator comes pre-subscribed to MSN Filter feeds.
I would personally like to have OPML import/export feature in feed aggregator.
