All in One computer.
I have an HP all - in - one that I like very much for photography, but I don't think it would be very useful for your needs. My gut feeling is that it would not travel well on a regular basis. And you would still need to carry a keyboard and mouse. To my knowledge, no one offers an AIO with a keyboard incorporated.
I still like soup. . .
Now that you've judged the quality of my typing, take a look at my photos. . .
