Details are sparse but apparently it was showcased in Germany recently. But per the article:
"Size of a grapefruit"
"an integrated system that exceeds the capabilities of leading game consoles"
“Today marks the beginning of a new era for Xi3,” said Jason A. Sullivan, founder, President and CEO of Xi3. “This new development stage product will allow users to take full-advantage of their large high-definition TV displays for an amazing computer game experience. As a result, this new system could provide access to thousands of gaming titles through an integrated system that exceeds the capabilities of leading game consoles, but can fit in the palm of your hand.”
Price and launch date please? For once specs matter less to me. Xi3 is a bangup hardware manufacturer. Their stuff is not the most powerful, but it has a enough punch, runs really quiet, and really low power consumption. Last I checked their base machine was $700 and had a bad intergrated GPU, but that was also a couple years ago.
Edit:
Per Xi3 website:

Also they go for about $500 now for their base level machine.
