Here is an example of the future of gaming!
Epic Citadel is a browser based benchmark with beautiful graphics and detail.
Walk around a stunning castle in First Person and take in all the eye candy while you stroll down streets, over a country-side and through a church.
The Unreal engine utilizes Java and HTML5 to communincate with your video card and I see a lot of possibilities with browser-based gaming.
Obviously we will still need a good video card, but as tablets can render these amazing visuals it makes me believe one day my desktop will be obsolete.
Note: Make sure to use Firefox in Linux because Chromium isn't supporting Unreal yet.
