Think that's easy? Let me tell you about my Dell Latitude E6400. One screw removes the whole bottom plate, giving you access to everything you can remove. Two screws and the hard drive comes out (don't even have to remove the bottom plate). It isn't as tough as the best of the Thinkpads, but it could hold its own with the current ones.
Probably the only line of Dells worth owning, though.
Dell's corporate grade stuff is FANTASTIC to work on.
(Well except maybe the clamshell cases on the Optiplex 150-280 series...) At work all our laptops are ThinkPads, but all the desktops and servers we buy are Dells. I just wish they hadn't brought the Optiplex 790 back to the stone age by replacing the eSATA port with PS/2 mouse and keyboard ports. It was faster to pop the desktops open and steal the DVD drive's SATA cable to image the things.
I can't think of many small laptops that are as accessible as the x100 line though. Half the videos on YouTube demonstrating how to replace the hard drives in netbooks are 10 minutes long and walk you through a complete disassembly, because that's the only way to get to them. There's no reason cleaning the heatsink in any
laptop should be this complicated
If I ever win the lottery I'm starting a business making replacement bottom halves for laptops so they can actually be serviceable.
