Computer or Robot?

I think that if there was a perfect computer for me, it would have to be portable, but I would need it to be able to have enough hard drive space for everything that I do on it, as well as be able to function very quickly with a lot of programs open. Most computers slow down significantly when you run more than 3 or 4 different programs at the same time. I also would like to specialize the computer. Some people think that a robot would be an easy solution. I disagree. Having a robot know exactly what you want to know because it can read your mind or something creeps me out signifcantly. Thus, I would like a easy-to-use, portable, fast, and easy to specialize computer.
