I got my first laptop with a digital pen and touchscreen in 2008 or so. They were rare back then, but nothing groundbreaking new. The touchscreen did suck though.
I don't know why you got downvoted, it's true. A lot of screens were touch screen even in the 90s, but they were typically single-touch rather than multi-touch capacitive interfaces. They were used a lot (and still are) in Point of Sale terminals, for example, where an employee needs to stand and ring up sales.
