While I'll agree that Vista is a whole boatload of codebloat (Frikkin' 500 MB of RAM used just sitting at the GUI). Exchange 2007 is a whole carton full of betterness than 5.5 ever was. Sure, if you had one mail server and didn't want to shell out the big money$ for Exchange 5.5 Enterprise edition to get over 16GB of a mail store, it did its thing, but so did Pegasus mail, Netscape mail and a whole slew of others. Be glad if you've never had to cope with a corrupted Information Store in 5.5. Exchange 2007 is a whole new beast when it comes to recovery with its Log shipping method of Continuous Cluster Replication. You cann have a backup store be hot standby until you need it. (I'm not going to defend the Jet engine though. That's a whole new topic) Even the install and management GUI is very straightforward. No more going back and forth between multiple consoles to edit Users and Server settings. Best of all is the Powershell scripting interface. If you wanted to you can build entire Exchange infrastructures straight out of the CLI. Woe be those who think fondly back to 5.5
