Here's a handy feature comparison chart :

In particular, if you need to :
1. develop for mobile devices
2. create/modify tables and stored procedures remotely
3. use a Class Designer and/or Object Test Bench
4. edit XSLT and not just XML
5. use deployment tools
6. use Crystal Reports
7. have source code control
8. execute remote debugging
9. have 64-bit compiler support
....you'll need at least VS 2005's Standard edition.
If you don't need those capabilities, you'll do fine with VWD.
The Standard Edition is $299 for full-install and $199 for the upgrade version.
At the bottom of the chart, there's a long list of items
which are only available in the Team System edition.
