It’s been a little while since we have heard anything about the rumored iMac Touch that will run both Mac OS X and iOS, but if the rumors are true, Apple is in the early testing stages of making this device a reality.

According to DigiTimes, which has a pretty good track record on Apple rumors, Apple is indeed testing the iMac Touch that we first told you about back in August off the back of a European patent filing.  Here’s one of the images in case you don’t remember it.

Currently the rumors are running that the screens would be 20-inches and larger, but that presents a problem with the current technology.  According to DigiTimes:

Projected capacitive touch panels are typically produced by placing touch sensors over the panel, and then a cover glass over the sensors. The conventional method is not only costly and complex, but affects display brightness.

I would imagine that Apple is pouring a ton of money into working on this issue, and they probably won’t release anything until it’s worked out as the company prides itself on its displays.

My biggest concern with this technology is how often we will be cleaning our screens.  As anyone with an iPhone, iPod Touch or iPad can tell you, you are constantly cleaning the screen for fingerprints.  Are we now going to see iMac sized protective shields?  Even those can get smudges, marks and scrapes on them, so it could get a tad annoying.

There is no real clue as to when we could see these released, but it does look like the concept is under definite testing.

What say you?  Are you ready for a tocuhscreen iMac?
