What is you definition of large? A thousand observations, a million, 50
million, more? Your biggest bottleneck will probably be how well SAS
can read the data from the HD or across the network. I used to think
50 million was big but when you start thinking of your datasets in
terms of the number of gigs of space they take up, then you are probably
looking at large datasets.
For "large" datasets on a laptop, you want to maximize your ram, the
speed of your hard drives (and their configuration) and your network
connection if applicable. Even the best laptops today barely come close
to a good desktop system. (Note: I'm assuming you already maximized
the CPU.) If you really are trying to work with large datasets in "real
time" dump the idea of a laptop and focus on a solid desktop. If, on
the other hand, your datasets are smaller than a couple of hundred megs,
a nice laptop will do just fine. Any laptop with a couple of gigs of
ram and faster hard drives would probably be sufficient.
