I own a few, a big PC laptop with a 19 screen, a small netbook PC, an Imac (just for work) and an older PC laptop running on Linux Mint.
But 99% of the time I'm using my big laptop or the netbook, the second being perfect to carry all over the apartment and use on my couch or in bed. The Mac never goes on the net and only serves for editing and the adobe suite. And the Linux running machine is just for pure Geekdome and serves mostly for downloading stuff.
