Acer is working on a frameless laptop with touchscreen keyboard that uses the back of the panel’s glass substrate as the cover – with potential release in the second half of 2010.

Coupled with a touchscreen keyboard, the rumored device should be impossibly thin by traditional laptop comparisons. Keep in mind that we’ve already seen this Frame Zero concept from Fujitsu and Acer’s arch-rival ASUS has been showing off its dual-display laptop prototype with touchscreen keyboard for months. Even the OLPC XO-3 plans to eschew the clickity keyboard in favor of a touchscreen version.

The design will help reduce the thickness of the ultra-thin notebook and can also reduce material costs.
Acer will also adopt a touch keyboard to allow the notebook to be even thinner.
