Touch but no multi-touch

I'm currently using an older Lenovo ThinkPad X200 tablet PC that has a touch screen, but it's not a capacitive multi-touch screen. Instead, it's a passive or resistive touch screen that only allows input from a single touch point. The tablet also has a Wacom Penabled digitizer, so I'm not limited to the passive touch screen.

What are the advantages of a resistive touch screen panel? For one, you can use any pointed object on this screen. Don't use something that will scratch it, but even if you're wearing gloves, you can easily touch the screen and navigate your apps. We're going to see fewer tablet PCs that come with resistive touch screens because most tablets will now include capacitive touch screens. I wonder if we'll look back someday and desire having resistive touch screens on our tablet computers.
