Based on my experience (and needs), I'd prefer a tablet with a separate usb keyboard, mouse, usb hub and OTG connector. The tablet alone covers 99% of my needs away from a desktop pc, except when I'm on vacation when I need a BYOD with a keyboard and mouse (it's actually a cut-down keyboard, such as you might see on a netbook). Advantages: cost (kb, m, otg & a very small powered hub cost me ~$5 each bought separately), portability (tablet only). Disadvantages: portability (though the whole ensemble may weigh less than a laptop/netbook, it's kind of a handful to juggle, can't really use it on your lap, needs power outlet as the kb+m are a ferocious battery drain). You can buy tablet cases with kb bundled, making the package a bit more convenient (and a lot more expensive). I don't know if I'd go for >7-8" tablet, depends on use case I guess. My nexus 7 classic is slow  :-@ but still usable  :-S .
