So why use VS 2008 if you aren't using the new .NET 3.5 features?
- Nested ASP.NET master page support at design-time
- Rich CSS editing and layout support within the WYSIWYG designer
- Split-view designer support for having both source and design views open on a page at the same time
- A much faster ASP.NET page designer - with dramatic perf improvements in view-switches between source/design mode
- Automated .SQL script generation and hosting deployment support for databases on remote servers
