i refuse to be stuck to a desk. 2 ruptured discs will do that to ya.
laptop or tablet for me
I remember a time not that long ago when I wondered why so many people thought laptops were necessary, never mind other stuff. Now I'm sitting here typing on one (though I normally *do* use it with an adapter and a Model M keyboard! :-), there's a tablet charging nearby, and I have a smartphone that has more CPU power and memory in it than many of the desktop systems I've used in recent times...
I rarely use my laptop any more. I use my desktop if I am home, and my tablet the rest, or my phone if I have to. Laptop takes too long to boot, even with an SSD
