Many of our database systems have made the slow migration to SQL Server 2005 just in time for the full scale appearance of SQL Server 2008. I have, over the years, used 'isqlw' for my shortcut to query analyzer from the run window. I noticed a while back that this no longer works for 2005, and that you have to type in 'sqlwb'.
I figured the difference is due to the fact that you can have both version run along side each other ... my muscle memory now has to reformat itself for a new short cut ... I do not cope well with change.
