The HP Envy series promises to be a big hit. It is the best laptop so far with "hybrid graphics" configuration: an integrated graphics card and a dedicated one that can be turned off. People has successfully been able to turn off ATI cards under Linux in two independent cases before: a Lenovo laptop and the Acer Timeline "G" models. See for example:

The ATI graphics card in the HP Envy models is also OpenCL-capable, and ATI has just recently released OpenCL Linux drivers:

This puts the HP Envy series in the perfect spot for Linux users that want the same level of hardware functionality that MacBooks restrict to OSX.
