You think running the SQL Server UI in 64 bit is really going to give you a perf advantage? :-} Nice attempt at humor. I believe the client tools are still 32-bit <s>
I build training videos and conduct database training using SSAS where I'm processing OLAP cubes that are as much as 80 GB, where one of the servers is a standalone server environment.
Same thing with MOSS and PerformancePoint Server - the 64-bit versions yield better performance to the naked eye, especially MOSS.
I know ETL developers who test out SSIS 2008 packages on their own standalone 64-bit machines.
As I said earlier, there are a number of database developers out there who are a mix of that "apples and oranges" you spoke of earlier.
