I actually thought of that, and was originally planning on opening a store for various maker projects (I'm working on a big crypto arbitrage desktop monitor) but the broken SBD peg kind of killed the idea. Although I could do something where I charge USD and calculate STEEM/SBD price on checkout.
Just not sure there would be enough demand to be worth it.
Probably not enough demand for the gaming console. However, an eCommerce solution with Steem payments could have a lot of demand.
I would start one if I could figure out how to reliably source goods from a drop shipper.
To me the good's sourcing part would be the easy part, just follow the shopify/amazon models loads of people are using. The hard part would be the payment/checkout system, as @themarkymark mentioned the SBD peg, if it ever gets fixed, it would be much easier to do.
