I agree Hugh - something like Windows Live Writer for me - but then yesterday I was reminded of a feature in Live Photo Gallery that I had completely forgotten about. Simon Hughes, our UK director for small and medium business showed me the panoramic stitching option in Photo Gallery. No, not some new form of electronic crochet but the ability to seamlessly take multiple photos and create a panoramic composite. If your director of SMB is waxing lyrical on this, you know you have a hit!
This is the kind of technology you'd normally see reserved for higher end, paid for, photo editing programs but now it's available to everyone.
I just wish we shouted more about this stuff....see what a skeptical user thinks after playing with it.
Granted we still need to improve the install experience as I agree with Tom, pushing people down the Live search route through the installer just reminds me of when you had to work around similar "tricks" with RealPlayer. Trust me, that feedback has been vehement internally.
