NOOO,
Please Apple, Don't Do It.

Their is no real reason other than to be a sales gimmick.
It's much faster and more intuitive to use a mouse on any desktop.
Imagine having to constantly, move your hands back and forth. From the screen to your keyboard.
If you have a 24 inch screen thats a lot of distance to move from corner to corner.

This is a nice concept if you have to navigate a interface. That has only a few options.
Such as a kiosk at the airport.

With hp's touch smart interface. You still need a mouse. To fully operate the windows environment. It is designed more for hp's priority entertainment package. Photo, music and document viewer.
 
Have a look at the Asus eee-top - a 15.4" all in one, touchscreen computer. It's atom-powered which is exactly right for the purpose (although I'm sure Asus will push it as a desktop replacement) and 15.4" is about the right size for a wall mount.

Thanks for the information! I'll probably get one after it is available.
 
I got to play with the HP one, and I found it worked fairly decent. What impressed me was the chassis it self. Very well designed for an HP.

Agreed their stuff has been taking a nice leap in design lately. The HP MiniNote is very nice little netbook.
 
Touch screens only work if they are horizontal, or at an angle, and you are above the level of the screen.

Their place is in mobile devices and pub gaming machines.
 
Purely as a personal opinion, I don't think touch-screen computers are the future. I think touch-screen peripherals/input devices are the way forward. As has been mentioned, the minging fingerprints all over your screen? Nah...

Take the current wired Apple Alu keyboard.

Now, imagine replacing the key-area with one large piece of glass with a display and multi-touch like an iPod Touch or iPhone with a 2/3mm alu bevel all the way round.

This would double as your keyboard and mouse/trackpad. Under normal circumstances it displays a QWERTY keyboard on the left and the num-pad on the right BUT- using software it detects when you're moving the pointer with your finger. You hold one digit on the surface and it recognises that it's not a keystroke and moves the cursor appropriately. Also, you could customize the right-hand side to display whatever you want. Weather updates, system info, RSS feeds.

Imagine what you'd normally see on an iPhone/iPod Touch screen playing music replacing the num-pad on the right. With multi-touch. It controls iTunes at a glance. Volume, play, pause etc...

Also, think of movie or photo apps- you can resize/move/edit using multiple fingers and the keyboard changes accordingly with it's built in LED backlit display.

I rarely use a keyboard for typing during iMovie- what if it was used to show an extended thumbnail of the current clip and you use your fingers to edit/trim it? You put your left finger where you want the start of the clip, drag your right finger across to find the end and 'swipe' the unwanted parts off the screen like removing an unwanted icon from the Dock or Sidebar.

Piano display for Garageband?

Fingerprint reader for system security/system updates/Keychain/logging on? Instead of typing in a password, you hold your thumb or finger over an Apple logo displayed white-on-black on the keyboard.

Multi-finger gesture that brings up the apps elect screen like when you press CMD & TAB? Except the thumbnails/icons appear on your 'touchboard' instead of your display?

Who knows...
