New(er) Nvidia-based Laptops:
I realize this is a thread for laptop's that work with PCBSD, but
here is something to "watch" out for if your looking to buy a new(er) Laptop.
Try to avoid this so-called "Nvidia Optimus" Technology for this reason, for now, (atleast 'till / IF ? nvidia provides a proper bsd/linux solution) :
(I'm well aware of projects like Bumblebee(linux) rev.-eng project, but it is far from ready for the big times yet, ...)
Laptops, to avoid if possible, with nvidia/Intel "Optimus Technology" are like, of course the cheaper, 555M, 540M or 330M, ..., are some example chipsets that I found.
And, Laptops with a "real" nvidia (chipset), like 360M, 460M, 560M, 580M, 585M are some good examples of NON-nvidia-optimus alternatives, that let you run nvidia, in Linux, the way it was meant to be run.
Unfortunately, these are also more expensive.
Choice is yours'.
btw: I don't condone, or support the above, neither am I against it,
I'm just trying to say, as we all know, if your next "new" Laptop is gonna be an nvidia-based Laptop,..., then do your homework thoroughly, before your spend your hard-earned $$$,
so that you'll be happy thoroughly, hardware-wise, in the long run.
Just a head's up.
