All of the issues he mentioned are Dell's fault, not Ubuntu's. If you take a "naked-iron" laptop, regardless of the manufacturer, and install a boxed version of Windows on it, it will be the same thing (if not worse): you will have to hunt down latest drivers, OS patches, BIOS updates and so on. Just look at the list in "drivers/software" category on Lenovo web site: yes, you have to install them all, and some of them are patches (!) for XP specific to Lenovo laptops, and touchpad configuration utility is made by Lenovo, not Microsoft. If Dell wanted to make end user experience flawless, they could have provided the same level of "OS-tweaking" to make sure their hardware is well-supported. In fact, barebone version of Ubuntu probably beats Windows by the number of hardware supported out of the box.
