xjessie2007, the fingerprint part of your comments should be related to the black rubber finish on the top of the screens, while the Dell Latitude system should have a smooth magnesium casing. The reason that the rubber finish is still there is for the benefit of the corporate users, whom travel alot between their office desks and their conference room without their laptop bag. These people just carry their laptop in one of their their hand, some people sweat alot in their hands, which when using the magnesium or regular ABS plastics cover may reduce frictional resistance, like car losing grip when the road is wet, causing in many cases the laptop to slip out of your hand and dropping it.
Also Dell's keyboards are no match for Thinkpad's Keyboard, many people buy Thinkpads just for the keyboard experience. No one have a better keyboard then Thinkpads.
Additionally have you tried upgrading a dell latitude laptop with Ram or open it up before??? it is truly a once in a life experience, you think parachuting is scary, wait to you try to upgrade a dell. Just read this post and there are pictures relating to the whole process.
http://www.notebookreview.com/default.asp?newsID=3750&review=Dell+Latitude+D630The Dell's power adapter for some reason are bigger than the pint size Lenovo adapter. My 17 inch XPS dell have a power supply that weighs nearly 1.2 kg, the Alienware (owned by dell) also have this sized power supply, with some proper training i think i use it like the medieval knights using their mourning star mace...
I am not sure about Dell laptop's look, no one ever have said a dell laptop looked good, maybe it is down to an acquired taste, if you stare at a Volvo long enough you may fall in love with the look.
Also Latitude laptop (5.2 pounds) should also be heavier than a comparably specced T series thinkpad (4.7) pounds). The power supply of Dell weighs 0.6 pound and Thinkpads i think is around (0.4 pound).
The Dell has two of its usb slot in the back of the machine, and the VGA/Modem/Ethernet ports are also on the back. I personally hate this setup, as i find the Thinkpads system of placing port on the side far more superior if you fly a lot or have cramped space.
Have a look at the link above and make up your own decisions as to whether you hate or like the Dell's Latitude's look.
I personally think the numerous ports on all sides of the Dell's laptop makes it look messy, the look from above when Latitude laptop is closed is definitely something quite beautiful, but when its opened the keyboard layout look like a mess just like my old Compaq EVO N1020V...
