The SQL Server group (and their product) is one of the very few things in Microsoft that has earned my deepest respect. Not Windows, not Exchange and, certainly, not ShamePoint.

I frequently rank Microsoft's product line as follows:

1 - Natural keyboard - the one there is no reasonable replacement for (the kinesis keyboards are 5 times as expensive). If there is a reason my none of my machines is 100% Microsoft free, this is it.

2 - their mice - simple, precise, comfortable, inexpensive

3 - SQL Server - it almost makes having a Windows server around worth the pain.

Having said that, I have enormous respect for PostgreSQL. It's a very solid RDBMS and it's my database of choice most of the time. It is more comfortable to use from a command line than SQL Server will ever be (which is OK, because a CLI is not a high priority over there).
