Yeah, that's real. You're seeing Donzilla 0.6, Microsoft Word, Microsoft Project (displaying the Donzilla roadmap), a SuperNES emulator (running A Link to the Past), a Nintendo 64 emulator (running Ocarina of Time), Adobe Photoshop Elements, and Windows Media Player (playing The Sisters of Mercy) all running at the same time.
I have 1024MB of physical RAM, and my pagefile boosts my system's total capacity to 1159MB of memory. At the moment this was taken, I had around 32MB of resources left. The bulk of the resources were Nemu64's 200MB, Photoshop's 100MB, Donzilla and ZSNES's 80MB, Project and Word's 50MB, Windows Media Player's 24MB, and then there's all my background services accounting for another 124MB... And, of course, processor usage didn't dip below 97% at all. Even more interesting was this configuration's time on batteries: seven minutes.
BTW -- That's resized from 2304x768 with two screens: one running at 1280x768 and another at 1024x768. If you want to have a look at the full thing, it's up at this link. Note that it's 2304x768 and almost 1MB in size, so I would reccomend you have a broadband connection to view it.
