HMD prices

[K_Freddie]

That really looks nice... but judging from their other products the number doesn't have any relevance to the resolution. Also take notice of a few things here..

The name of the PDF file is 'Vuzix_Wrap_920AV_Brochure.pdf'. AV usually stands for Audio-Video, and I summise that it's probably HDTV format compatible res of 720x572 upwards, but not higher than 800x600 Real res.

Another give-away here is .. from their website.

PCs & Laptops with S-Video

S-Video is an analogue interface and inferior (resolution wise) to the digital I/Fs of todays graphics cards.

This tells me that the product is more geared for the Audio/Visual market where lower resolutions are more acceptable.
edt: A bit of sarcy here - Why would I watch TV through a pair of 'sunglasses' ? Then again I don't suffer from 'gadget-mania'

One thing that one must consider when looking for high-res, and good picture quality lcds, is that the LCD must have a digital interface (analogue I/Fs are generally not good enough). This makes this type of HMD a bit more bulkier than Vusixs glasses, but I think the trade-off will be worth it.
