While as @ChrisHoffman points out that the future of PC's may include touch screens, I don't see a need for a home system where I have to be close enough to touch the screen. Maybe I'm old fashioned, but I like the idea of a home system that can do what ever I want it to, with any program I wish to put on it (not some small, chunk of an app cut from it's main, or full program. If I want that it's for a mobile platform like my new tablet ), and when I'm on my home system I like to be comfortable weather I'm leaning back, or sitting up and not have to hold the screen I'm looking at, which being large enough to watch a movie comfortably, sits any where from 1 to 6 feet from my reach. I found cordless keyboards and mice a boon to my computer experience. Now when you're talking mobile platforms, I prefer a laptop that can handle any full programs I can throw at it as well, because if I carry a laptop, I'm simply mobilizing my home environment ( a removable, wireless keyboard and mouse would be nice here as well, for when I'm chillin') a touch screen might be useful, but, I really don't see a need for it as I'll mostly be using a keyboard, which means to me I'm not going to be comfortably close enough to touch the screen anyway, so give me a mouse. Now with my new Tablet ( I just broke into the tablet scene with the second gen Nexus 7), I'm finding it would be helpful to have a keyboard with this as well, as when I have to type the screen keyboard takes up so much room I'm not comfortable with not seeing the whole of the little screen that I have, plus, holding the tablet while typing, even when it's just a couple of keystrokes, I find a little awkward. I'm seriously considering buying a keyboard for it but can't find something that combines the attributes I'm looking for, but all told, for the most part, using my tablet, touch is the main reason for carrying it around to begin with. A small form factor that fits in a pocket without any extras to carry around and does most (not all) that I need to do while on the go. This is my opinion as a mixed user/admin with light work and light uses for mobility. I just like tech and playing with it.
