Management Studio...grrrrrr
Dear oh dear "much easier to work with", "nicely integrated"...I use Management Studio every day and every day I curse its hopeless clunky interface where it takes 3 clicks to do what used to be possible with one.
To be fair EM had it's faults (like randomly shutting down ever so often), but QA was a nice tool that did a simple job and did it well.
Change for the sake of change, and not well thought out IMHO.
