Re: External monitor for laptop
A higher res monitor is only going to go as high as the laptop will let it. With an exception of Wide screen... you may see some different numbers there. It'll be the same, just wider :P
You can get a docking station if you want... only thing is if you get one that plugs in to your Laptop via USB then you have monitor, keyboard, and VGA or DVI going through usb. If you game this might not be that great...
I would stick with just plugging the monitor, keyboard, and mouse in when I get home. It's just three cables... and really the difference in time between plugging in 3 vs plugging in 1 is like 5 seconds lol... up to you though!
Edit* Sorry, some laptops are built to be docked and have special connectors on them. If you have one of those (or if I did) then yes, I would get a dock. It's build specifically to transer data more effeciently.
