Laptop with eraserhead mouse & NO trackpad

I have been using a Sony Viao for the past 8 years & it is going to die & I need to get a new laptop computer with a touch screen to replace it. I love the eraserhead mouse it has, as well as touch screen. I HATE laptops with the trackpad in the font of the keyboard. But, they ALL have them. Does anyone know of a new (or not too old) laptop computer meeting these parameters. Thanks!
