If you only need to take one or the other, that's better than carrying a heavier combo device.
That the combo device is heavier is a fact not in evidence, and indeed, with current ones varies greatly by the device; an ASUS Transformer, for example, is not substantially heavier than any other 10" tablet, nor are most of the convertible Ultrabooks much heavier than any other ultrabooks.
If you can do real work on a keyboardless tablet, and travel with only the tablet, more power to you -- I know a fair number of people on FT claim to. I can't.
