all them are portable. "portable" as in "you can carry it to places without dealing with cables. just close the screen and carry it under your arms". depending on how strong you are, it will vary if they are "portable" as in "carry it around daily" enough. try to experiment with weights on your bag to see if you are OK with it. that would be my best recommendation.
finally, another considerable point that is, at the same time, very personal: to me, what really defines portability is the size, not the weight itself. To me, it does not matter if the laptop is thin as a paper sheet, if it's that big, carrying it will be a hassle anyway.
