I agree Management Studio is a step in the right direction.  Let's hope it's more stable than EM.

A couple things I wish they would have carried over from EM:

OBJECT SEARCH

What a handy tool. Why on Earth would they drop this?  Sure, you can use the INFORMATION_SCHEMA views, but it was nice not to have to crank out a new select statement each time I want to find all the occurrences of "InvoiceNumber" in a db.

Also gone is the ability to copy a table from EM, paste it into QA and have the Create Table statement done for you.  Not the end of the world, but it was handy.

Maybe they will add these back in one day?
