Features on SQL Server 2008 - Katmai

For the last three weeks i have been playing around with SQL Server 2008 (Katmai) CTP. I managed to install it on Windows 2003 server without any problems. Although i would advise people not to install alongside SQL Server 2005. If you want to use management studio of SQL 2008 CTP be sure to use the developer edition CTP, the expression edition only comes with some client tools. Since its a CTP and you only are trying to get your head around new features it is useful to have management studio installedAs with any CTP i didnt know where to start and i found that Chad Boyd ihas listed the new features for Katmai quite extensively on his blog. Since I am just a developer and i filtered the list of features that may be more useful for a developer to look at.. I m planning to plough through one feature at a time and put up some information on this site for people who are interested.
