If you start the installation for the new Visual Express 2005 (beta) developer tools you will need more time while installing because of the additional download of the tools (.NET Framework 2, ...).
If you have a look in the C:\documents and settings\[USERNAME]\local settings\temp you will find the folder VSESETUP where you can find the complete installation files. Copy this folder to your laptop will help you to save time (and perhaps money if you do not have a cheap internet connection).
Note: I did not test these files, but the eula.txt and other files a from the Visual Express 2005 tools!
