One Laptop Per Child has unveiled its latest concept of a future XO laptop, the XO 3.0.

The 3.0 is more of a tablet than a laptop, and it’s $75 projected price undercuts OLPC’s as-yet-unrealized $100 goal for the first XO by $25. The tablet would feature a screen courtesy of ex-OLPCer Mary Lou Jepsen’s display technology startup Pixel Qi.

The tablet looks pretty fancy, but it’s just a concept with a target date of 2012. Last month, the Cambridge-based nonprofit killed plans for its similar-except-foldable XO 2.0. Also, founder Nick Negroponte told Forbes, “”We don’t necessarily need to build it. We just need to threaten to build it.” So you might not want to hold your breath.
