Move on to VB .NET

I am learning VB .NET now but I haven't started working on any major project. Do you think I should move on to .NET or work with VB6 for sometime (app how much?)? I am thinking that it would hard to distribute your application when the end user requires to install a huge .NET framework and it doesn't run on Windows 95, 98 anymore (does it?). Also, can I use the activex controls created in .NET in VB6 and make then run on Windows 95 or higher?

I believe the framework works on 98 and up, but not win 95.

That's good if it works on, at least, 98 but I was just curious if you could create an activex control in VB .NET (using some of the .NET controls in it) and then just use it on any operating system you want to.
