I really the like the customer & vendor dashboards - the ability to attach any file to the customer data base in Estimate is great! Categorizing items is also a big help. We have a lot of items we use the retail items plug-in to price & it is nice to be able categorize them now. I am sure there are more features that we will use  after we convert to 2011.   I have used Estimate since 2003 from Version 1 to Version 2 & now 2011. Every version has come out with  more great features.
