You can kind of get that now with the 360-degree rotation laptops, which are available with Windows or Chrome OS. I haven't used a Windows one, but Chrome OS behaves pretty nicely as a tablet.
The trouble though is, once you get an acceptable laptop keyboard and a corresponding screen, the resulting device seems excessively heavy and bulky when flipped over into the tablet form factor. You probably won't want to hold it up for more than 10 minutes.
I like the idea of one all-in-one device, but it's hard to see a way around these things. The cheesy tiny portable "keyboards" they make for tablets are pretty lame for extended typing, but better keyboards are too heavy for tablets. Meanwhile, I expect a desktop device to have the compute horsepower and RAM that are tough to get in a proper tablet form factor.
