Form Team: Thank you all for the great information! The one issue that does seem to stick out is the graphics card business and the screen output vs images or plots. The quality associated with anti-aliasing is new to me. Presentaion quality needs to be addresses, esp if I'm going to use RenderWorks (options?). If we assume RW, should I then only use a computer with an NVIDIA card (model?) to get the best display and output quality? I like the idea a laptop's mobility for client communications, and would consider the MAC because of usability, but my MAC store says that only ATI cards are avail in MAC laptops (an odd history I'm sure). In addition a VW tech support's FAQ describes the unresolved ATI anti-aliasing issues. Yes, I do need a new computer (Pack. Bell. P-II/Win95). It old, runs on soft coal but works great. I think VW+Land+Render is a bit too much load.[Peter Cipes - I'll check for your email].
