Microsoft will announce tomorrow that they are buying VDI vendor Calista Technologies. They will also announce an expanded partnership with Citrix where Citrix and Microsoft will jointly market their virtualization services.
Off-the-record rumors of a big acquistion by Microsoft next Tuesday (tomorrow) started circulating last week. Then today Forbes magazine (accidentally?) published an article with a publication date of tomorrow about the Microsoft aquiring Calista and expanding their partnership with Citrix. Oops.
I'll have a full analysis of this deal tomorrow. In the meantime, you can read what I wrote about Calista Technologies last year.
