What makes you think you can't keep doing the same things you were already doing? Mesh is just an option. You can still make prims and sculpties, if that's what you want to do. The only difference is now you can import mesh models, too.
Prims and sculpties aren't going anywhere. Use them as long as you like.
It's so funny how SL-centric users think of mesh as some kind of new thing. Mesh IS the oldest way to make things there is, when it comes to 3D modeling.
Thank you for this answer. I came to the forums to find this answer too although I am not a creator and this post is the most clear answer I ever read here though I don't visit the forums everyday and I might have missed a lot of mesh discussions.
SL users especially the buyers are all confused including me cause upto now from what I read here and there it gave me the impression that as time goes I wouldn't be able to see prims and sculpties and that they would gonna be unusable.
Mesh might be the oldest way to 3d modeling but is a new way in SL so we the users that are not 3d designers but just simple users think of mesh as a new thing. :womanhappy:
