If you're still debating about whether Microsoft's IPTV software is full of bugs or production ready, the Register has a write-up
with Microsoft's response to AT&T.
If you're wondering whether Microsoft's IPTV has the right feature set, Microsoft reveals the results of a 7,000 person survey asking what features viewers would most like to see implemented. "They want whole home DVR, multiview and VoD services and an easier program guide."
Additionally, T-Online France is full of praise for Microsoft IPTV and says "it has been ranked number one in features by both benchmarking organizations ip-label and Witbe, and voted as the system with the best features by Journal du Net."
