I understand the decision ... but the "impression" being left about is starting to get negative.
2008 is barley a year old yet the changes to R2 create waves of implications. Other MS prodcuts arn't certified on it. Applications _introduced_ in 2008 have alreayd been removed (servermanagercmd.exe in core for example). New Forest exclusive modes to leverage potentially great features that in practice are clunky to the average admin (no GUI at all for the ad-recycle bin? I dont know a single tech who likes the idea of doing powershell queries instead of the drag and drop they are used to).
2008 and R2 are huge leaps forward in secuirty and configurability but these areas of polish that have been neglected are sadly the first thing most daily admins will see ... and thats just going to leave a poor impression and alot of techs to simply sit on 2003 a little longer until all this is sorted out.
