It's gadgets like this Matrox 8-way video card -- which lets you drive eight 2560 x 1600 displays at once -- that make me think seriously about going back to a desktop machine and abandoning laptops. If only I could find 1) room for eight displays and 2) a graceful way of using the home partition on my laptop as my desktop's home partition as well, without sacrificing speed (NFS), or having to reboot each time I sit down.
