Microsoft wants to make sure you can use their touch screen sooner, rather then later. N-trig Ltd., a start-up that makes touch-sensing screen hardware, is expected to announce that Microsoft is the largest investor in a $24 million round of funding. The software company is making the investment to help N-trig quickly make their technology work well with Windows 7.

What they didn’t say was exactly what size the touchscreen will be.
