Take Domain Name for Our Website

First thing for Hi-vista, change our website www.interactive-projector.com's domain name to be more professional, but simple to remember easily.
I think www.optictech.com is OK. This name can include all possibilities for the products we'll operate independently in the future.It can explain well that the optic will be as Hi-Vista's main technology for interactive products. It regards to company's positioning, brand's positioning and so on.. We need study more.
