Apparently, Samsung and Nokia are racing to put out virtual keyboards. These keyboards will be integrated into their mobile phones.
I'm not a huge cell phone user, but phones aside, I've got to say, I love the new keyboard alternatives that have been coming out in the last couple of years. More options for those of us with painful hands.
And having tried text messaging, I can definitely see how a virtual keyboard would be more ergonomic (and easier to use) than trying to type messages using the number pad of your phone. I wouldn't expect 80 wpm and accurate touch typing using one, but they look like neat toys to try next year when they are scheduled to come out.
