I've played with others' Resolume setups and want a nice rig to work with on my own. Every setup I've seen has used a laptop, but I have some VR projects planned (namely Microdose VR) that may be too demanding for the laptops in my budget ($2000 for the computer and projector).
Is it practical to VJ using a desktop? If not, are there any laptops in the $1500 range that would be up to snuff? I don't mind buying used/refurbished.
