I'd be willing to bet good money the Rift is considerably lighter than the HMD you describe using!
If you really cant see the potential of VR finally being technically possible then I feel bad for you son :(
Two key points I feel I should make:
1. Decoupled aiming with a Razer hydra or something is the first thing pretty much everyone who pre-ordered a Rift devkit plans to implement.
2. While the resolution is low, it is still an early prototype. Top of the feature list for the commercial version is; higher resolution screen.
