Chromebook Lusting

This past week I've researched a lot about getting a Chromebook, no, not the little one; but a powerful one, the C100 is really under powered.
Looking for the Samsung Chromebook Pro, the Asus Chromebook C302 and, yes, maybe the one, the Pixelbook.
Leaving price aside, and just for the sake of lust and more lust, the only thing that is really stopping me is how close, how unfriendly to customization Chrome OS is.
The hardware of those laptops is amazing, specially the Samsung Chromebook Pro and the Pixelbook, (doh!)
