I would take a good look at the Dell Latitude E series with available docks
loaded with connections galore.
Without knowing what your desired laptop specs and budget are it's difficult to offer more specific recommendations. If you're looking for a good deal, I would seriously consider this Hot Deal
before it expires.
Two upgrades I would highly recommend are backlit keyboard and 1080p LCD. Not only are they incredibly useful they will definitely help increase your laptops resale value, many years down the road.
You can purchase your docking station with your laptop (recommended see below for pricing) or separately from here
E-Port, dock for charging, digital video, and USB / eSATA port support [$129.00]
E-Port Plus, dock adds dual digital display and legacy port support [$199.00]
forums is a good place to get solid advice.
By the way there is a dedicated computer forum
here on WHT.
