Try the search button because just couple days ago someone posted his experiences. Bloat, instability with busy systems, Linux boot CD (you need to buy upgrade once support for newer hardware is required), poor user support, poor update mentality, no polished HIR, no walk-up-and-Backup like IT edition, slower compression and overall performance, incremental engine inferior, .....

Jack of many trades, master of none.
