This seems to heavily dilute the Surface brand. Until now, you could get a Surface device and know you were getting a useful, independent writing/touch surface and a good-to-great keyboard/trackpad to attach. Now we're given a laptop with no convertibility whatsoever; not even a 360 degree hinge like many similar-spec laptops?
It started as a table. Moved to a tablet. Then a laptop. Brand dilution doesn't seem like a priority for Microsoft. Wish they had more sensible and less confusing naming. This is not fun to explain when people ask. (Same can be said of Google and a bunch of other tech companies too though.)
It's an euphemism considering the whole windows mail live hotmail with skydrive now onedrive thing.
