The early reports all show VB7 to be primarly based toward web development, COM+, and windows DNA. To take advantage of the majority of these feature you will need to run Windows 2000 Professional (Workstation) as your OS. Your install base will also be required to be Win2K. Many of the Internet features will require Windows 2000 Server as your OS. I suggest you reconsider VB6 as your dev choice.
