The age old topic... support support support..... We have apps that do not uspport SQL 2008 yet so we are stuck on 2005. It takes time when you buy software packages and implement them to have them support the latest Service Pack, then the app folks have to start a project, allocate time and do the dev, test, pqa and prod testing, checklists etc... One SQL 2005 we are still on SP2 because the apps versions do not support SP3. Heck, we still have some stuff on SQL 2000!
