Yesterday, I presented a SaaS overview at WSA. For those interested, you can find the slides I used here. Being a .pdf the animations did not go through, but it should give you a good sense of what I talked about.
Following my session, I had a few very interesting conversations with ISVs in the Seattle area re-architecting their applications for SaaS. I'm looking forward to engaging with them soon.
Speaking of ISVs re-architecting for SaaS. I will be at the WW Partner Conference in Boston in just over a week. If you will be there and want to chat. Let me know.
