Standard version of VS 2008?

Question

I'm currently developing in Visual Studio 2005 Enterprise which I use through my employer.   I also have an Academic version of VS 2003.   I want to buy my own copy of Visual Studio 2008 so I can use newer versions of the .NET framework (3.5) and WPF.    I intend to use it for C# and C++  development (and I want to try out STL/CLR), about half desktop-app and half web-app work.

If I'm used to an Enterprise version of 2005, will I be satisfied with the "Standard" edition of 2008?   I don't really want to spend more than that if I don't have to. 

Any "gotcha's I need to know?

Is there any upgrade path so I don't have to pay list price?

Thanks in advance.
