Laptop is too small.
I pack a 6-foot folding table, an overclocked, water-cooled alienware PC with dual 22" monitors (one for DD, one for spreadsheets/DTBC and QBBC reference charts/depth charts/etc.), a 2-hour power supply backup, wireless router and a backup ethernet card and--as a third backup--a 56K modem, 2 cell phones & a bluetooth headset (one for secretly negotiating trades with other owners on the other side of the room via voice or text so no one can listen in, the other for research on players [i have the "Key Club Personnel" contact sheet from the NFL Players Association with cell numbers for all of the Assistant Coaches, trainers, and general managers for each team--if I need to decide between DJ Hackett and Justin Gage on draft day, it only takes one quick call to Tennessee to see if Gage is still dipping his right shoulder on the go routes, which could easily make all the difference in fantasy]), my Aeron swivel chair, four bottles of Gatorade Frost, five Nature's Valley energy bars (alcohol and salty snacks will absolutely wreck your mind by the middle of the eighth round), and a 19" TV hooked up to my DirecTV receiver (I bring my dish on an 8' extendable pole that I mount outside) so I can go picture-in-picture on NFL Network and ESPN News. I also have a alpha-numeric pager I wear on my belt (I call it my Batman Utility Belt) that I've preloaded with contacts at all the team's local sports beat writers so I can contact them in the locker rooms and at the practice facilities, so I'll know the status of Ronald Curry's ligaments before it hits the wires. My other league owners don't know this, but I also bring something I just call "The Switch", which I secretly plug into my power supply... I picked it up at The Spy Store, if things in the draft start going in a way I don't like I just flip the switch and it sends out an electro-magnetic signal that messes up everyone else's laptops and cellphones. Obviously all of my stuff is shielded and grounded.
