A while ago, I wrote about Some notes on multi-touch and Windows.
Today, Dell introduced the S2340T 23″ monitor with multi touch support, aimed at Windows 8. It surpasses the minimim requirement of 5 fingers:
It also features a multi-position, articulating stand, a 10-point touch and Full HD 1920 x 1080 resolution.
This comes much closer to Microsoft Surface Table. Hopefully that SDK will fully support this monitor.
