Do we really want touch screen monitors?

Engadget:

Sure, it's not the real thing, but those of you aching for a taste of Steve's "research project" touch Macs can now order up the latest and greatest iMacs retrofitted with touchscreens from Troll Touch. The company's been putting its PSRT touchscreens on all sorts of displays for years, and much like the ModBook, the tech pretty much just works. Pricing for the new iMacs starts at $2499 for the base 2.0GHz 20-inch model and runs up to $3899 for the 2.8GHz 24-inch Core 2 Extreme, while those of you who want to upgrade your existing machines can get in on the action for $1099 (20 inch) or $1599 (24 inch). Shipping now, apparently.

I can imagine that you would want a touch screen on a device you can hold in your hand. Let's say a phone, or even tablet PC. But is a touch screen on a desktop computer really desirable? The screen I use at work I cannot reach with my hands when I'm working and to be honest I would like to keep it like that (better on the eyes). Do we really want computer touch screens?
